[quote="DGFone"]Am I the only one bothered by Simba's voice? For some reason, it sounds a bit too... deep.

Different Voice actor, it happens but it makes sense, Simba is older than the first TLK, if we assume Simba in the first Movie was, lets say 18 Years old Human wise, and TLK II or Return of the Roar he is at least mid twenties this can happen, males technically still have developing bodies until sometimes early 30's
Personally i don't mind it and they have done the best they cant to find a voice actor that close
