I'd say that the anime starts out relatively strong with season 1. Even then, the time travel mechanic was super suspect. It's never abused the way it should be by people that have any actual semblance of a brain, and things that should have been caught onto with time traveling to the future does not get explained until the event happens in the present.
However, and I said this in season 1, but if you frame the show in a way that just has Takemitchy be a normal shounen protagonist without powers, the show becomes a braindead, but fun show about high school hoodlums fighting it out against each other. In a way, I appreciate this over shows with superpowers, because the fact that there is nonstop fighting makes a lot of sense when you put it in the context of aggressive gangs fighting over each other.
I'd also like to point out how even an average adaptation like this one can really make the show shine. I read the manga, and I have to say that it was extremely boring. Despite being the same material, the anime brings out something that the manga did not. And it's not like I'm going to be gushing over the animation. In fact, most fights are really short, unsatisfactory, or slideshows. Even so, it's average. Maybe below average. The voice acting is good, no complaints there. Storyboarding, choreography are very standard and mimic the manga, and yet the drama that unfolds on the screen is much better than the manga. I mean, the manga was so boring I actually forgot what happened, so watching it in the anime again felt like watching it for the first time.
Overall, this shows the power of even just having a mediocre adaptation can make a series watchable.
