From the minute I started the game, I was disappointed with it. None of the charm from the original translates into ToS2. We're given a small slew of uninteresting characters that are just about as explained as some of the minor characters in the original (like Dorr or Pietro). The only thing weaker than the story was the dialogue.
Some other immediate turn-offs include: Intolerable main characters, unacceptable graphics even for a Wii game (that is to say, the graphics made me feel like I was playing a dreamcast game), a very slow adaptation of the battle system that was originally designed to be fast-paced.
To be perfectly honest, as a fan of the original, I find myself very hard-pressed to find a single good thing to say about this game.
