Just got home from seeing this movie and I'll have to admit, I really enjoyed it.
KA is definitely a Braveheart/Gladiator wannabe that doesn't quite live up to the storyline of the aforementioned films. I know critics have mentioned that there is no character development in KA and they are right, but... to be fair this isn't a character driven movie. I think Fuqua and Bruckheimer assume that most people know the characters and therefore they give us a war romp.
It's fun... and I honestly think it beats "Troy" in it's enjoyment factor. And what's not to love (and drool over) but Arthur, Lancelot, and Dagonet (a surprise hottie!)
Typical Bruckheimer fare. Example (won't ruin the movie)... there's a scene where the gates of the great wall are being opened and Arthur is going to ride thru. The gates open and all you see is smoke for about 5-10 seconds before Arthur turns the corner and glamorously appears. Bruckheimer at his best.
Enjoy the movie.. but don't go in expecting Oscar fare.
