However millions of people enjoyed this film, when i watched a copy I got from the library about a year after it went into theaters, I just found it a little overrated. I thought that it was too long to keep with, (I usually avoid films over 2 hours and 15 minutes becuase they get boring early.). It has some entertaining stuff, but I was bored for most of it. Also, aside from it being mediocre at times, the PG-13 rating was defiantly accurate, concerning that there are violent scenes which may be disturbing (reason why it's a pause), and some heavy romance that both are very iffy for children under 13, despite that it is popular with kids. (in Canada this movie got a 14A, which has the same restrictions as a our R rating, except it is 14 instead of 17 and the content is more PG-13.)
When I say that this film is violent, I mean it, it's even implied that a character bled so much a medic had to syringe blood back into him. I didn't have much time to write this, but one more thing, however the smoking in this film is controversial to some, in the DVD's subtitle menu, there is a anti-smoking PSA.
Sorry I found Avatar mediocre. I just couldn't enjoy it.
