A couple months ago, I rewatched X-Men and X2 and was pleasantly surprised to find that they held up well. While they did choose to create their own story wholly separate from the comics, they managed to get the characterizations right and made a couple of solid comic book films.
The plan was to watch through everything in the Fox X-Men franchise, but as soon as it came time to watch X-Men: the Last Stand, I couldn't do it. I vividly remembering hating it because of how poorly it used the Dark Phoenix storyline. But, I did finally end up watching it about a week back. And it was still shit. lol There were some decent things that happened and it wasn't as terrible as I remembered, but it still wasn't good by any means.
Unfortunately, I think tonight is the night I finally watch X-Men Origins: Wolverine. Which, if I remember correctly, was even worse than Last Stand. We'll see though, as I'm still gonna watch it. It's been a while, so it's worth giving it a shot even if all it does is remind me of how bad it was. I'm really hoping whatever the MCU does with the X-Men is better, but I have a feeling nobody is ever going to adapt them in a way that's as satisfying as having read the comics. At least, not while Disney is doing it and caring more about making money than telling good stories.
