(Bad) Masamune-kun no Revenge

Series in one sentence:
An incredibly scrawny and bland-looking anime kid, that the rest of the world considers attractive, is still too charmed by the bitchy girl he wants to take revenge on.

Series in more sentences:
A high school boy who used to be overweight in his childhood is left hurt after getting denied by his crush, thus plans to take revenge on her years later by making her fall for him, only to deny her afterwards. But even though he's considered a heartthrob by every girl in school, things still aren't going that smoothly, and there are many people standing in his way.
 

I cared so little. In fact, I did not care. The characters in this anime were either anime clichés or just downright uninteresting, despite the attempts made to give them a personality and backstory. And sure, perhaps they had both these things, but I doubt it anyone can pick out a favourite character in this bunch of bores. Even Toradora! had fun characters. How can you not even make one of them likeable?
No matter the person on screen, their motives never made sense; I even thought the main guy was wasting his time with his lame revenge plan at one point. Seriously dude, is it even worth the effort. Go live your life already, just take the redhead, damn.

None of the episodes leave you satisfied and the ending was especially lazy. The school musical episode was pure overdramatic nonsense and there's no resolve at the end.
The sole reason I kept watching this anime is because I started watching, but it was so standard, it definitely didn't entertain me. It's a shame, as the plot sounded like a good drama or a good comedy. I suppose it tried to be both, emphasis on "tried".

I would've given this series an "average" rating, but I honestly feel my time's been wasted by this show. I don't even want to give it points for the plot concept.
