Is Godzilla 1985 the best?

I wouldn't really say any film is the best. It's all opinions. To you Godzilla 1984 is your favorite. To me Godzilla Final Wars is my favorite.

Probably not the best move but it spawned the best Godzilla era. Since it was the only era with recurring characters and an actual continuation.

I wouldn't say the Heisei era was the best. Just because something has continuity and recurring characters doesn't make it any better or worse than anything else, but in the Heisei series case it really didn't matter. Most of the recurring characters were never very well developed and seemed to make appearances just for the sake of continuity instead of story. As for Godzilla 1985, the American cut is probably better paced. But I didn't like all the strange edits and crude propaganda. Raymond Burr's character adds very little to the movie with the exception of connecting it deeply with the American cut of the original film. Now the Japanese cut is superior, but much slower. It's more like a cumbersome disaster film than a straight up daikaiju film-- Not that this is a bad thing, because it sets it apart from things done before. I wouldn't rank it as one of the best movies, but it's very relevant and probably one of the top best of the Heisei series. Love it or hate it, both versions are interesting films to study.
