Yeah, its always fun to get a new character, but generally, unlocking a new character means getting very good at using another one... so really all your unlocking is... POTENTIAL...
All jokes aside, yeah I like unlocking new characters but I prefer unlockin new skins for existing characters so I dont have to change my gameplay style (Or unlocking new characters RE4:Mercenaries style where its still the same gameplay but new weopons and new looks)
Also I dont play online and I imagine coming up against someone with a better character that you have to unlock is not funzies.
