Of course. Why would it be?
XIII has no redeeming quality whatsoever. It lacks some form of sensible and well-written story, has a terrible cast of characters (and villains), battle design that was half-assed and huge step down from X or XII, being one massive hallway simulator with no towns or backtracking or some form of exploration outside of one area, no interesting sidequests or minigames, no towns, no NPC to chat with, spawned 2 sequels, has Lightning (worst FF protagonist ever) in it, etc etc.
The less spoken about the game, the better.
