In a way, I totally agree.

I like all three eras for different reasons. I like the Showa Era because the cheap, all practical effects give it all a campy and/or underdog feel, but you can still take the movies seriously. The drawback is, a lot of people don't like it for the cheap effects and that's understandably fair. I like the Heisei era because it's one, continuous story. I think the drawback from that era is that the suits are too complex and as a result, a lot less mobile, so instead of a bunch of guys wrestling each other you get beam battles. The Millenium era is great because it has really fun, really enjoyable, self contained stories. There's no worry about continuity at all. The computer special effects though? They totally don't hold up.

Personally, I think The Millenium era films would have stood the test of time better if they avoided CGI as much as possible and stuck with practical effects. Model tanks, jets, missiles, the whole nine yards. At the time, the visuals were passable, but nearly two decades later and they stand out and detract from the films. To kind of illustrate what I'm talking about, look at movies like Alien and Star Wars. Those movies are from what, the '70s and '80s, pretty much zero CGI, and they still look great.

I feel like traditional Tokusatsu effects can still be impactful and fun, but for them to work, the philosophy and methods of the style needs to be embraced as much as possible.
