1. King Arthur - Tamed down version of Braveheart. If you like Braveheart, you'd like this. The special effects were good and Arthur and his knights are easy on the eyes for the ladies, while Guinever is definitely a must see for the guys.
Guys will love watching the battle scenes, while the ladies will like the story line. Some romance involved but no gratuitous nudity/sex scenes.
2. Terminal - Nice drama. Not much action to it, but of course you'd know that. Tom Hanks does a nice job as a lovable guy and you really feel for him in the end. Ladies will probably need some kleenex in some scenes. The guys will probably feel the movie's a little slow at times. Some very laughable humor here and there and the movie moves at a pace that's tolerable.
If I had to choose one to see in the theatre: King Arthur. The Terminal you can watch on DVD without loss of detail. King Arthur is a movie you want to watch on the big screen simply for the battle scenes.
