Had Biollante been sucessful

I agree, they are two of my favorite movies, and Biollante is one of my favorite kaiju. What you sited above is why I think the 90's and Mellenium series' don't really do it for me. (Godzilla 2000 and Godzilla Vs. Destroyah aside). Every series starts off strong then tapers off in my opinion. It's because the budgets fall, and the development time goes right down with it. 

There's a lot of "what-ifs" with the Heisei series. What if Kawikata had been given the opportunity to do darker films had vs. Biollante been a success? Would the effects have improved instead of declined? What if Ishiro Honda had stayed alive long enough to direct Godzilla vs. MechaGodzilla II? Would it have been the best movie of the series? What if Godzilla vs. MechaGodzilla II stuck with its original ending: Godzilla's death and Baby absorbing his radiation to become the new Godzilla. Would audiences have accepted it? Would it had segwayed into an American film as originally planned? Would vs. King Ghidorah through vs. Destroyah even exist had vs. Biollante been a box office hit? No telling, but there's a lot of alternate paths that start immediately with vs. Biollante.

Good topic. Wish I had more on my mind to contribute outside of questions leading to more questions.

I think had they followed the direction Godzilla vs Biollante went in the series would have essentially stayed the same. As toho has made it clear they will bring back their most popular monsters in every series, so while Ghidorah's movie might have been different, there'sno question in my mind he and Mothra would still have gotten 1.

Yeah Biollante is awesome. I would like to see her back and maybe taking over monster island. The story with Biollante make more sense than another monsters against Godzilla. The director of Godzilla 2014 says he'll like do a sequel about Destory All Monsters, maybe we will see the return of Biollante.

I so agree with this, Biollante is my absolute favorite monster it would have been great if it had been made into a trilogy, maybe with the return Biollante.

Yeah, Biollante would be a very interesting monster to revisit. Compared to other Toho monsters Biollante has a lot of flexibility and unexplored potential; unlike many Toho monsters which have been basically exhausted or never had that much depth to begin with.

To be fair though, it wasn't JUST the performance of Biollante's movie which caused Toho to put the character in the closet and collect dust. Godzilla 85 has to share a large part of the blame as well. Neither film was that financially successful or very well reviewed at the time of release. It's estimated that even Godzilla 85 only made about 10% profit margins, and Biollante most likely lost money.

The reason why 85's performance is key, is because in the past, if a single Toho character premier didn't go over well (Anguirus, Gigan) but the SURROUNDING Toho films were successful, then Toho would usually give that character a second chance down the road, even if it was a move to save costs. But characters that had weak premiers and were surrounded by weak neighbors were harder to revive. 

So after two financially disappointing films in a row to kick off Godzilla's return, Toho had few options left but to retread the tried and true formulas and characters. And it worked for them, much the same way as these constant super hero sequels keep working. Mothra, King Ghidorah, and Mechagodzilla (and even Spacegodzilla) all saw their films make 25%-50% or more profit margins, even if those movies may have been more generic than Biollante's film. 

That all being said, if Godzilla 2014 inspires Toho to get back in the game, I would love to see them revisit Biollante :-)

Maybe they wouldn't have made the god awful sequel that was Godzilla vs King Ghidorah if biollante had been successful.

84 and biollante were in their own league of awesome eighties science fiction films, can't really be touched in my opinion. The eighties were awesome when it came to originality in creature design.
