Just went to watch the movie today, found it a great watch (personally). I remember being a wee little tike when the animated disney version came out and i practically grew up on this movie (along with Sword in the Stone). When I was 12 I found it was based off an even earlier version - so i watched that too.
Anyway after watching the movie, and being a AiW fan, I have to say: Imo it was a bit fast paced. Instead of characters going: <Slight pause> That's odd. They just went: <instant reply> That's odd, So it made it a bit fast paced if I may say so. Some of the acting seemed forced and not lively enough but the world was fantastic to feast my eyes upon.
Overall I give it a 7.5/10 and it's worth watching if you enjoy these type of movies.
P.S. I watched it in 3D
