Can I skip the TV series and just watch the movies?
This is just my opinion, but if you watch...
Death and Rebirth - You will be too confused to even enjoy the movie.
EoE - You will miss the entire point of the show.
Rebuild 1.1 - Good if you want to go through the first 5 episodes in an hour and 1/2.
Rebuild 2.2 - Don't even think about it.
So IMO, no, just watch the show. You'll thank yourself for doing it too.
