Mob Psycho 100 III definitely has its weak episodes, but makes up for them tenfold with its peaks. The finale is quite literally one of the best I've ever seen, the ones leading up to it are great too, and even the first few episodes and midway point of the season are just incredible. 

I love how the fact that Mob is avoiding his powers is almost withheld from the audience, as we know he's trying to become independent but it never gives us a reason to think that could be bad, yet it makes total sense when two parts of his identity become split. 

That plotline not only serves as Mob's final outburst to lead up to the end of his arc, but also is a perfect excuse to go around showing us how each character has changed because of him and give them all the chance to end their arcs and do what they can to help Mob. The best of all of these is easily Reigen, throughout the series we see him deceive Mob but clearly like him and feel bad for using him. Confessing is the natural conclusion to his character and it's done to perfection, him running after being inspired by Mob as the first opening plays was one of the craziest moments of the series. When we see Dimple possess him, then Reigen take over to come clean about being a liar, we get hit with two subversions. One, for a moment we think Reigen has powers which is seriously insane, he's of course just possessed by Dimple but it's hilarious in normal Mob Psycho fashion. Two, we learn the title of the episode - Confession - was never really about Mob confessing to Tsubomi, but about Reigen to Mob.

That ties in perfectly with Tsubomi rejecting Mob, and them instead building a friendship together, just as Mob has learnt to do with everybody else. The series knows that real relationships with people come from that and it won't give us some bullshit of Mob getting the girl that he hardly knows more than the other guys do any more. Leaving it open-ended works perfectly, they could go on to be good friends or it could turn into something more but either way it would be from Mob using the social skills he's learnt all series, not from some cheap writing.

This honestly became a review for the finale, but I guess it ties in to the themes of the rest of the season so it's fine I guess? Anyway, I loved the season overall it retains all the beauty the rest of the series has had and just has writing that's the slightest bit better. Dimple being alive was a little bit BS though.

10/10 would watch again
