Lighten up
I've read quite a few negative and positive write ups about this movie. Lol, (seriously, I'm laughing while writing this) it's just a movie! God da?&$! If you are looking for a deep philosophical commentary, pick up a book. If your looking for just good silly fun, then enjoy. Seriously, If you are expecting Hollywood to educate and inspire then don't hold your breath, as that sort of thing is slow and coming. Even those kind of shows, when they do appear, have detractors. Since one can research a movie before watching it, you've no one to blame but yourself for being disappointed.
Read books and study if you want a history lesson. If you want to shut off, relax and go along for a fictional adventure, this will work. If not, turn the channel or turn it off
