Any specific suggestions?

I heard Return of Godzilla (1985) and 2000 are pretty good. There's Mechagodzilla interpretations in both the Heisei series and Millennial (Godzilla vs Mechagodzilla 2, Godzilla against Mechagodzilla and its sequel Tokoyo SOS). Godzilla vs King Ghidorah of the Heisei series is another loved one. Also, the final movies of Heisei (Godzilla vs Destroyah)and Millennial (Final Wars) are fun rides too.

Well I finally got around to watching it today and this movie was awesome! With it being my first Godzilla movie I was on the edge if my seat most if the way. The CGI was top notch and was an all around great movie.

The fight scenes were well done even if some were short but man the way Godzilla handled the two Muto's! It was just great and sort of made me want to watch some of the older films.

Overall I'd give this movie a 5/5 and I am now really excited to watch the sequel, and maybe this one several more times.

Godzlla 84
Godzilla vs Biollante (my second favorite)
Godzilla vs King Ghidorah
Godzilla vs MechaGodzilla II
Godzilla vs Destoroyah
Godzilla 2000
GMK (my absolute favorite)

I'm really sad that Godzilla isn't on bluray in the UK. All the blurays on Amazon are US imports.
