Avoid at all costs the recent American made version, although having the the little godzillas slipping around on ball bearings was funny, the film as a whole was awful.
I thought the new Gamera trilogy was well done as well. Other new Godzilla you might like is 'Tokyo S.O.S.' and 'Godzilla vs. Megaguirus'.
I just got my hands on the new Gamera trilogy blu ray boxset. Amazon is selling it for $8! Just got done watching the first one, and I quite enjoyed it! I'm going to finish watching these before I move on to the newer Godzilla films.
How are the special features on the Gamera Blue Rays?
