I liked most of the plot changes except...

The pushing of the V/Evey romance and the fact that Finch went to Larkhill

Spoiler

but did not take LSD to relive what V went through.

I mean, does every Hollywood movie have to push a romance? The love factor made it almost Phantom of the Operaesque, which I did not get from the GN at all. I was alright with Evey being much older in the movie than she was in the book, although a bit of the "growing up" process was lost because the change was less drastic. I found it sweet that V was almost like her father in the novel and read her bedtime stories, but him pining away at her bed in the movie? Meh.

That also meant that the Gordon/Evey relationship had to be toned down since OMG we can't have a third wheel! I think the fact that V steals Evey from her happy life in order to show her what freedom truly is, pushes the point in so much further than him "rescuing" her from the Fingermen and then torturing her. Happiness is a prison. Being satisfied with your lot in life is a prison, as Gordon's death in the book demonstrated. So many people die being unfulfilled in their lives, because they spent their living moments trying to "get by." That was one of the statements in the novel that really hit me, and I was disappointed that they didn't show that in the movie.

The other statement in the book that also hit me was the revelation that Finch had at Larkhill - that no one imprisons us except ourselves. What was with that "we are all connected" malarkey in the movie? I didn't understand the significance of that at all.

I also missed the colorful way V spoke, which was mostly in iambic pentameter. That was damned cool, that plus the fact his speech was always puzzling. The movie character presented too much of himself and how he was feeling, IMHO, which I suppose tied in with the whole romance bit.

I did like the part with the people of London walking towards the soldiers. That was awesome. I also think that V met with a more fitting end, although it was waaay too much bullet-time for my tastes.
