Angels and Demons Book to Movie Discussion

I loved the book Angels and Demons, but the movie was kind of a mixed bag for me. I mean, they didnt change the Plotline much, however I think they did dispose of what made the book so great (such as the twist really wasnt that epic in the movie, and numerous reviewers stated that the film "refused to die" because of the twist). Also, I dont like Tom Hanks as Robert Langdon. I liked the casting otherwise (especially Ewen McGregor), and the way they constructed the Vatican was great. But it really wasnt that great. What is everyone elses thoughts on the Book to Movie Adaption?

Book>>>>>>>Movie
I didn't like the plot in comparison to the book. It felt incomeplete.

It wasnt that bad of an adaption. Some things were left out and some were changed but it actually stuck pretty close to it's source material.

The adaptation wasn't that bad. For a movie, it was pretty good. For some odd reason, I prefer the movie "The Da Vinci Code" over "Angels and Demons", but I prefer Angels and Demons the book over The Da Vinci Code novel.

There were some some scenes re-edited and done differently mostly for the sake of the movie. It's been quite a few years and when I watched the scene where he goes up on the holicopter, didn't Robert Langdon go with him. But, the guy only had one parachute. So Langdon had to jump out without a parachute but somehow survived either by his coat and landed in the river? It's been almost 5 years since I read the book.

I didn't like it. Seeing each murder take place seem repetitive, where as in the book, there was plenty of reading length between the murders to catch my breath.

SPOILERS :

I cant understand why I slightly liked the Da Vinci Code a bit better, but some scenes in Angels and Demons I liked better like : SPOILERS The bomb sequence was stunning. The huge blast went out then the shockwaves falling down was spectacular, and Ewen going up in the helicopter with the bomb was emotionally great. But the movie was kind of average, not bad or anything. Im not saying its a bad adaption, but I thought it could have been better.
