My brother was always dying to see this movie, so we both watched it, it just wasn't funny, if you still want to watch it it has some issues:
1. Mr. woodcock abuses his students, comic faling for laughs, mr. woodcock and josh have a violent wesling match,
2. mr. woodcock cheats on josh's mom, a woman says she's a sex adict, josh hides under mr. woodcok's bed as mr. woodcock and johns mother have sex, many other sexual refrenses and inuendos.
3. some language icluding: B--ch, D--n, h--l, a-s, and s--t.
So overall this is apropriate for kids 12 or 13, but that dosen't mean they'll like it.
