A matter of fact I just got home from seeing it. Literally 5 minutes I walked in the door from it. I personally have never read the books but have thoroughly enjoyed the movies and cannot wait until the third movie comes out.
I thought at some points it was a tiny bit slow but overall it was good. The battle scenes were easily the best part. I haven't seen such intense fighting fighting on the screen for awhile.
I think I like the Two Tower better though than the first one.
