To be fair Fairy Tail has two cases of "villains" turning good that are done fine IMO, with Jellal and Mest/Doranbolt (granted, villain might be too strong, but certainly an antagonist).

It's just that Fairy Tail has too many former enemies switch sides... far too many, so naturally some of those switches will undoubtably be less than great.

But between "Mister Justice" and "a certain dragon race" even Rave has 2 antagonist-to-protagonist conversions that were far from great with just 's change being well done.
