The reason I prefer the Eternal V-cinema as my number 1 choice is because I feel Toei knew they could do more with Eternal and his crew, and they sure did.
Getting to know the origin of all the other NEVER members was also terrific.

I thought the Chaser movie was pretty fun, but I have to give it to the Eternal movie. It was really damn fun, added a lot of dimension to the A to Z movie, and had a lot of Minase Yashiro running around in short shorts.

Phew, hard to say. I generally enjoy the Sentai V-Cinemas much more than the Rider ones. I guess Eternal and Chaser are my favorites, though Accel was also pretty neat :)

Chaser, with Knuckle being a close 2nd.

That V-Cinema gave GREAT characterization to Chase that he really deserved, and did a lot of interesting character dynamics that were needed in the Series. I will admit, though, the stuff with the girl & her brother didn't quite go much to anywhere, but still, regarding Chase's character, it was great, and surprisingly better than most of the Gaim V-Cinemas. (Baron's & Duke's are possibly the worst....)
