Query: Decent first half, GREAT second half... Eastwood is perfect!

This was a very good, not great movie. It is a bit slow at first, but you will find that there are just so many little things about this movie that are great. Eastwood is perfect: excellent acting, flawless direction... and he's got some of his typical one-liners. Definitly see this movie.
