I've said it before and I'll say it again, the zaniness of this film is so over the top that it compares well to the best of the showa films imo. Too me its just a very fun movie. From a technical or storytelling perspective I agree, this film is lacking, but I feel that is a critique people can throw at most Godzilla movies. This movie to me is a film I can watch sober, drunk, with friends or just put it on as background noise while I'm doing other things. Not every film has to be like Gojira or Godzilla vs the Thing for it to be enjoyable. So I will take my terrible gaijin actors, my ludicrous time travel plot, pokemon-esque dorats, cheesy terminator knock-off, and incredibly creepy great grandpa/great grand daughter incest subplot and keep pimping this film like the fun, satisfying trainwreck it is. Almost all the post KG films are so painfully by the numbers it almost hurts to watch them.
*edit* seriously though, G85, Biollante and KG are really the only Heisei films I consistently watch.
I have almost nothing serious to add to any conversation ever.
