Godzilla '54 is a great start. It's dark and serious, so it doesn't match the tone of the rest of the Showa era, but it's pretty powerful. If I could expand on that just a bit, not that you have to watch these films, but just to talk about the evolution of the era a bit. The next film in the series is Godzilla Raids Again and due to a rushed production, it's a bit of a flawed film. However, it lays down some groundwork for future vs. films. The third film in the series is King Kong v Godzilla and this is where Godzilla becomes more of a colorful character and we the series take a tonal shift into being action and adventure oriented. The fifth film in the series, Ghidorah the Three Headed Monster is where we see Godzilla first take on a hero role and on the series evolves from there. There are some really good resources about Godzilla's history that I'm learning a lot from. I think pretty soon I'm gonna make a thread about what I've been reading and watching, because obviously none of this I'm learning through conducting my own research and there's tons of good stuff out there. Besides, credit should be given where credit is due. :)

I only watch Cloverfield once every few years, but each time I take away something new from it. I can promise you the heroes aren't as annoying as you remember. At least, I kind of like them. :) The only thing about that film that I don't like is that the filmmakers put in a couple of scenes and images that are reminiscent of 9/11 and I'll definitely go over that when I get around to reviewing it because I definitely have opinions on the matter. I will personally say that each time I've seen the film, I've liked those scenes less and less. That said, they do such an amazing job with so many other things, it's still a great piece.

I totally agree with you on Pacific Rim. It's just a treat. I haven't seen that film in years, but I recently rewatched the Cinema Wins video for it and it reminded me of so many reasons of why I like that movie. I'm not as personally as generous in my views towards it, but that doesn't mean I don't find it just delightful.

As for Godzilla '98, it's honestly not as bad as people make it out to be. If it had come out under a different title, it probably would have been better received. For tons of obvious reasons though, it just doesn't live up to the public perception of Godzilla or his legacy. All that aside, it still has quite a few flaws, but viewed as an experiment, it's an interesting piece.
