This is a very late review, and I haven't watched it in a while to be fair, but I'm kinda mad, so I wanna rant about this shit.
This Season, in my opinion is the downfall of the My Hero Academia Anime.
The Overhaul arc is one of the biggest flaws in the story from what I have watched like I could see someone enjoying it, but personally, I couldn't even do that, with how many fucking flaws are in this arc, it's ridiculous, I wanna say that I loved bnha, but this arc probably marks the downfall, and I dropped it in season 5 from that boring ass training arc.
But this isn't a review of Season 5, it's one of 4, so let's dive into that.

Characters.

The best part of the season is its characters, but it's also part of why the season is not that good, I mean the main cast is basically the same of course, and they're pretty consistent if I'm going to be fair here. I love the main cast for the most part, while not all of them have incredible depth, I would say the character designs are very consistent, and I just love most of them because of their personalities and all that lol. The ones who do have depth, like todoroki, or..., anyways, the ones who have depth, are written pretty well, well that's for the main cast at least. The writer tries to make overhaul's character have depth but his character is written like utter shit at times. His character design is okay at first, I guess, but it goes downhill, his quirk is just mad unappealing to look at, which if that's the point, kudos I guess, but I don't think it is? Now I'm not really sure that's a full-on criticism but like, it's just part of his character, and while his quirk isn't the reason, he is the most underwhelming character and just badly written character of the MHA I have consumed.
They give him a backstory during it, which 100% is cool most of the time but like damn, it makes him even less compelling than he already was, which wasn't much. The backstory is that like his father figure type is like hospitalized or whatever and like he's actually trying to reinstate the yakuza and all that bullshit to like save him. The thing is that he like exploits, and kidnaps, a fucking child. So no matter your view on gangs, the mafia, or the yakuza, this does not, whatsoever, make him a sympathetic bad guy, the author tries to make him view as such, but fails miserably, it's actually dumb, his story wouldn't have been sympathetic that much either way, but still.
I like eri, and I love some of the characters that joined this season, I literally cried when sir night eye died, and I love hawks, and what the author does with endeavor's character, this and next season, I also love Mirio Togata.

Story/Plot.

Also probably the biggest failing of the season is the overhaul arc, which is where most of my criticism towards this cour lies. Damn it's just poorly written, when the fuck did this story get to a point where we're battling yakuza with some dumb quirk removing shit and like quirk drugs. Like this shit is just dumb lmao.
I personally love the Pro Hero Arc, and the U.A. School Festival Arc, and, Remedial Course Arc is fine I guess, but the overhaul arc takes up way too much of the season for the other stuff to overcome it, The fight scene in overhaul with deku and eri, while some of the animation was pretty sick, just wasn't that good, it was kinda boring and disappointing, It wasn't that hype, visually it was pretty sick, but the story is just not enough to make up for it, like yeah let's use this little girl to make bullets, it just doesn't make that much sense lmao. and like I said in the character tab, I just think Overhaul's backstory tries to paint him in a sympathetic light but just fails, like he's using a little girl to make bullets.
I think the entire yakuza shit is just dumb, like drugs in mha! Woooo...
it's just dumb lmao.

animation, music, fights.

not much to say, animation is decent, music is fine, and the fights are fine except the overhaul one, while everything is fine, like I said before everything about him and the arc is just stupid, so the fight is just stupid, I know deku is going to win, blah, blah, blah.

non-overhaul arcs.

There's good stuff about this season, but the overhaul arc is the longest, and the worst one. I was super hyped by the last episode, I love the endeavor stuff, I thought the gentleman antagonist guy, had really well-written motives, a cool character design, and was actually compelling unlike endeavor, that arc was really great IMO.

Over(H)all (hahahahhaa get it?)

Overall the season isn't that bad, but the bad stuff is some of the worst of MHA, and some of the longest of the season, so of course, that's going to make it worst, I think this season somehow has some of the worst and best of MHA in one like the final arc is some of my favorite of the series but just isn't enough to redeem the entire season.

Overhaul Arc - 3.9/10
Remedial Course Arc - 6/10
U.A. School Festival Arc - 8/10
Pro Hero Arc - 9.9/10

(This is just my opinion if you enjoy or think this season is good, good for you!)
