Controversial character design changes in game remakes

[Zkuq]

Strictly speaking not a remake but a remaster instead, but I think Assassin's Creed II didn't quite nail it:

I haven't played a lot of remakes though, so I'm not properly qualified to answer. Still, respecting the source material and keeping true to it is what I like to see, so anything that deviates too greatly from the (spirit of the) original is either bad or controversial to me. The same goes for sequels and such too (if you want drastically different designs in sequels, feel free to create new characters instead).
