Really 2.8? I have seen much worst with higher ratings. It wasn't amazing, but better than a 2.8!
If your standing on some moral high ground and want to take politics into consideration than sure -3.0, but i watch movies for story, content and a chance to escape reality if just for a moment and this was definitely at least worth the watch. To be exact I would give it a 6.9 out of 10, especially when compered to half the garbage that passes as 5 stars these days.
On a last note, if your under rating this film due to moral grounds,than consider boycotting any production from Disney or any large studio for that fact!
