Unfortunately, I watched this movie in math class one day. It is probably the worst movie I have ever seen in my life. The reasons are threefold:
1. Generic Plot- The plot is SOOOOO generic. It is basically taken straight from history (Greek, WWII, etc.) textbooks with changed subtitles and characters.
2. Predictability- Aside from atrocious animating and terrible script, this movie is way too predictable. I could guess everything that's going to happen.
3. Math/Plot Issues- I'll just make a short list here of big mistakes in the movie.
-The line "No equation can't be solved" is wrong. (Ex: x = x+1)
-If irregular shapes are illegal, isosceles triangles should be illegal (only equilateral triangles are regular)
-If shapes get more sides with new births, shouldn't all shapes be circles? Flatland doesn't really look like a new place; all shapes should have become circles from many generations of births.
