I didn't know whether to laugh or cry watching Moebius. It was ridiculously poor on every level and as a mathematician it physically hurt me to watch this. Absolutely zero research was done on the mathematical aspects of this movie (which is a main theme of the plot). I hope anyone who has the misfortune of seeing this movie can appreciated the irony of this in the final scene with the notebook.

Most of the maths is little more than random collections of words strung together (and the word Hausdorff underlined multiple times on a blackboard). At one point he walks into the end of a topology lecture as the professor is concluding "so remember, if a physicist tells you time has frozen, he's not crazy". Later when he is supposedly writing down complex mathematical equations you can see the notepad he's holding has a game of naughts and crosses drawn on it! Even the internal mathematical logic of the movie is inconsistent.

I know this is a student film and has other political themes, but I still think more effort could have gone into this, and not just the mathematical aspects. At the end of the movie, the guy is told "let's just forget this ever happened". I wish I could.
