I'll echo the sentiments of the game not really respecting your time. It's never blatant, but there are so many little moments that build up into an experience that borders on excruciatingly slow at times.
- So many moments where the level design is stretched too long or too thin, usually via unnecessary backtracking. I'm not just talking about the egregious moments either; there are so many times where you're forced to retread old ground for no reason other than padding. Flurrie's necklace, all the elevators and locks in the X-Naut Fortress, trekking down three separate hallways just to fight Gloomtail at a dead end, etc. So much of the game could've been streamlined.
- Not an unpopular opinion, but there are some story moments that are just really damn annoying for no reason. Bartering with Flavio for the Chuckola Cola, having to walk through Keelhaul Key a second time to get the stupid wedding ring for the stupid Piantas after sitting through that awful dialogue exchange, having to jump on General White a dozen times to wake him up, etc. Again, it's a much longer list than it should be.
- This one might be an unpopular opinion, but the segues between each chapter grew old quickly too. The Peach ones I can live with, even though they grew a bit long in the tooth by the end. But the Bowser sections? Hated them. Why was he even here? Just keep him as a Glitz Pit easter egg and call it a day, he didn't need to be in this game at all.
- Even the moment to moment gameplay has a few annoying quirks. Having to wait for the star power to fill into your meter before you can act is a mild annoyance that adds up very quickly, and it's even more aggravating when the star meter is already full. The transition time into battles is a bit excessive too, although that might be due to hardware constraints.
Add in a few broader complaints, like the lackluster level design, disconnected world, and middling narrative, and I'm left a bit conflicted. I still love this game; the characters are a lot of fun, the presentation is incredible, the vibes are just lovely, and the core gameplay loop is very strong. There's just so many small things that snowball into bigger issues that hold the experience back. It's still one of the best Mario RPGs and the best Paper Mario game (at least that I've played, never played Color Splash and it's been years since I've played Super Paper Mario), but I don't think it's the untouchable masterpiece that a lot of people make it out to be.
The direction of the modern games is still faulty at its core though, and I hope they take the positive reception from this remake and combine it with what people loved in The Origami King to craft something truly special. The pieces are all there, just gotta fit them together right.
