I was actually thinking of making a thread like this, myself. But, since you've already gone and done that for everyone, there is one game I've been meaning to bring up.
Zapper: One Wicked Cricket.
It came from Blitz Games and Infogrames back in 2002. The reason a lot of people seem to really hate it is because they somehow think it's a Frogger ripoff. It's nothing of the sort! You hop around tile-based maps and collect... stuff. That's about it. It was certainly inspired by Frogger, and it's sort of the spiritual successor to Frogger 2: Swampy's Revenge, which was developed by a lot of the same people as Zapper. But, even that game was rather a far cry from the traditional Frogger formula.
Frogger has broad, open maps. Zapper has more "Get from here to there" maps. It's like Serious Sam vs. Doom. However, Zapper also has puzzles in it, crates to smash, a lot more things to collect and the character himself can actually kill stuff, which is something Frogger just can't do. Or Chip, the star of Chip's Challenge, which I think is a lot more like Zapper than Frogger would ever be.
A lot of people also hate it for being short. Portal was short, too. And it was almost exactly the same as Narbacular Drop. Yet, people praise it for being "original", and hate on Zapper, when it's hardly anything like Frogger to begin with. On the surface, one might remind you of the other, but the similarities you come to assume start to disappear when you actually play the game. Comparing Zapper and Frogger is essentially like comparing inFAMOUS and [Prototype]. They're both sandbox games that give you superpowers to play with. But, when you actually do, you realize these games have almost nothing else in common.
If one game is inspired by another, is it really that bad if it's more advanced, puzzling, challenging and just overall better?
Plus, the soundtrack is just all kinds of awesome.
