The Basics:
A metor strikes Japan, unleashing an army of insect like kaiju that only the combined forces of the JSDF and Gamera can defeat.
The Plot:
http://en.wikipedia.org/wiki/Gamera_2:_Attack_of_Legion
The Kaiju:
Gamera:
Looking slightly different from his 95 appearance here. He now has permenant spikes on his elbows and his face has thinned out a lot. This is a fan favorite Gamera suit.
Legion Soldiers:
Pretty cool. A step up from the tiny Destroyer soldiers. Very alien like in appearance.
Legion Flower:
Pulled right out of Ultra Q, which is fine by me because I love Ultra Q!!
Legion Mother:
Really awesome kaiju pulled off in the conventional man (men) in suit method! It almost seems impossible to believe that men can fit inside that suit but they do making for one of the most incredible kaiju design ever put on the big screen.
The Acting:
Great all around, with the standouts being members of the JSDF.
The SPFX:
While Gamera: GOTU had some pretty good effects, G2 knocks it out of the park. The best kaiju effects put on film up to that point. There's some wonky CGI with the legion soldiers swarming over Gamera, but it's still better than the practical effects used in Godzilla vs. Destroyer for essentially the same shot. The suits used in this film are among the very best ever for a kaiju film.
The Other Stuff:
-The Legion seems like something pulled right out of Ultra Q, which combined with the very Honda esque film, really makes this feel like a fan boy dream cross over of Gamera/Ultra Q.
-Gamera gets some Showa era battle damage in this film, nice to see him rise up and score a win after being wounded so badly
-Not a huge fan of the way Kaneko sometimes pulls monkeys out of kaiju's butts for "SUPAAA!!!, Epic!!, Finishing MOVES!!!!!"
-This is probably my personal fave of the Gamera trilogy, though G3 has my favorite scene in it
-The science used in this film is incredible, it seems like Kaneko did some research for this film, and Legion's life cycle, and it shows
-The English dub for this film is about as cheesy as they come
