Tedfoldol everything you have heard about this movie is true.

Dynamixor The performances transcend the film's tropes, grounding it in characters that feel more complete than this subgenre often produces.

Siflutter It's easily one of the freshest, sharpest and most enjoyable films of this year.

Keeley Coleman The thing I enjoyed most about the film is the fact that it doesn't shy away from being a super-sized-cliche;

lulupalooza A woman-child, in pigtails the whole time, compulses by knocking and counting random numbers while depending on magical thinking. She has severe Obsessive Compulsive Disorder, debilitating anxiety, and is grossly stunted emotionally and mentally. Her father is completely disabled due to his own mental illness. So the film tries to make something of these very troubled people. However, it fails. It is difficult to care about the main character since she barely utters a word and runs away from most anything, which voids meaningful character interaction. In fact, it's difficult to care about any of the characters. Most of the school children are written with cliché, and urine has its close-ups that do not advance the story. There are too many ridiculous plot points, like someone being hired for a sensitive position without an interview or credentials, a highly unlikely instance of weapon wielding, a sweetly stalking male, an older person leaving behind something hard-earned to get lucky, and an unbelievable ending to make your eyes roll out of your head.Apparently in this filmmaker's world, home-study approval is not a requirement, much like teaching certifications...and worthwhile scripts. 2 out of 10.

Claudio Carvalho After a stroke of her father (John Shea), the weird Mona Gray (Jessica Alba) gives up of all the things she likes but mathematic expecting that her father will be better. When she is 20 year-old, she is expelled from home by her mother (Sonia Braga) to live her own life. Soon her mother lies to her friend Ms. Gelband (Marylouise Burke), who is principal of a school, telling that Mona Gray is graduated and she hires her to teach mathematic to the third grade. Mona Gray feels affection for the orphan Lisa Venus (Sophie Nyweide) and her odd behavior attracts the attention of the teacher Ben Smith (Chris Messina). When there is an incident at school, the life of Mona Gray changes for good."An Invisible Sign" is among the worst movies I have ever seen, with an awful and senseless story. The plot is imbecile, beginning with Mona Gray's mother expelling her daughter out of her home without any reason. Then Ms. Gelband hires a clumsy and unprepared teacher without checking her credentials or background. Instead of mathematic, Mona Gray actually teaches and is attracted by numbers. She brings an ax to a classroom with kids in a total irresponsible attitude. The corny and lame conclusion, with Mona Gray rehired by the school and easily getting the custody of Lisa is terrible. The worst is that, this is the type of movie that we see expecting to like it, but the awful story is unbearable independently of the cast. Last but not the least, Sonia Braga lost her beauty and is unrecognizable. The years are cruel for everybody!My vote is two.Title (Brazil): "Matemática do Amor" ("Mathematic of Love")

TxMike I found this one on Netflix streaming movies. It is quite quirky in places, which may turn off some who enjoy conventional narratives, but in total it is a very nice little story. Jessica Alba is the adult, 20-something Mona Gray. As a small girl she loved her dad, ran with him, did "numbers" with him, and overall became somewhat fascinated with numbers. But as she grew up her dad developed a mental problem, he could no longer function normally, and as a 10-yr-old Mona thought if she did certain things, for example if she denied herself of things she enjoyed, her dad would get better. All this caused Mona to grow up with development challenges, and she became very shy and unwilling to experience normal friendships, not to mention a love relationship. But one day, to help her, mom found out the local elementary math teacher had run off to Paraguay to join the revolutionaries and Mona was to be the new math teacher. Never mind that she never finished college!So Mona jumps in there, does the best she can, has difficulty controlling the students. But she meets Science teacher, Chris Messina as Ben Smith. he is pretty much the opposite of Mona, outgoing and not overly worrying about anything. He takes a liking to Mona but finds her shell very difficult to penetrate.J.K. Simmons is interesting as the neighbor Mr. Jones, who had taught math to Mona as a child, and who now runs the local hardware store. Her confused dad is John Shea as Dad. And Sonia Braga is her mom, still attractive at just past 60. I first saw her years ago in the 1983 movie "Gabriella" where in her early 20s played a sultry cook and lover. Interesting career arc!Anyway it is a nice movie, and therapeutic for Mona, as she eventually finds a way out of her shell. I have enjoyed Jessica Alba since her days as "Dark Angel" on the TV series, and I like her here.

eman1440 I suffer from OCD and often find myself counting telephone poles as I drive, cracks in the walk way, tiles on the floor. This film portrays the inner workings of such a mind that literally had me with my mouth open at times because of how much I could identify. The story is powerful, with layers of themes, and the child actors are excellent, not to mention a hefty substantive performance from Jessica Alba. If you are a cinephile that is jaded with Hollywood's current offerings, this is definitely a thought provoking film that will leave you with a smile and some bewildered expressions on your face, unless of course, you are like me.
