Transformers 2 Revenge of the Fallen is a rock em sock em thrill ride and a very good summer escapist film. If you are going for heavy drama, don't bother with this one. But, the show Michael Bay delivers is a good time and he gives you your money's worth of entertainment. Just go and have a good time! I would recommend seeing it in the Imax format to get the best of the effects.
If you are going to see The Dark Knight just for mindless action and chase sequences (although there are several terrific action scenes) you are bound for disappointment. This film has a lot to say and does so with high style. The performances are all top rate (yes, Heath Ledger does some of his finest work as the Joker!) with everyone involved deserving to take a bow. But what I enjoyed the most was that it all had a point and it was made with intelligence. Very worthwhile and entertaining but a lot more seriously themed than many people would have expected. I could go on and describe the great photography, editing, film score, etc. but you definately need to see this film and judge for yourself.
