What could Toho have done better?

Won't argue there, but I mean what could TOHO have done better, not really counting the American one here

The Showa movies are mostly fine, particularly through the 1960s. Even the 1970s are more compitent than first glances percieve.

My issue is the later films. A lot of it has to do with Toho being very demanding, Koichi Kawikata becoming lazy and the overall talent not being half of what Honda, Tsuburaya, Murata and Sekizawa were. Toho prefered to cut costs by making nobodies within their studio first time directors for Godzilla movies-- often it didn't pay off. Even when it did it wasn't that impressive.

The Millennium series has a sense of more artistic freedom than the Heisei series did, but it's still strangled by Toho's rushed production schedules. And the while the crews were inspired, they weren't up to par.

If anything could have been done better it's that Toho could and should have found more time and greater talent to make both the Heisei and Millennium series better representations of modern day tokusatsu. Instead they merely exercises in the style at best. Though, admittedly, enjoyable exercises.

Well, they didn't have good computers back then to animate stuff as good as the newest godzilla films. They only thing they could have put in, in the old movies would have to be better actors and maybe a touch up on godzillas costume once in a while.

Better actors? The 50s and 60s consisted of the best Japanese actors in the country at the time. 70s-00s... Okay not so much...

Not sure how the costumes were even made then, but considering they were constantly experimenting with them I'd assume they did about as much touching up as possible... Except in vs. the Sea Monster and vs. Gigan. The suits were literally falling apart on screen in those films.
