FFVIII. One of the few FF that is simply quit and couldn't get into after getting into the second disc. I couldn't have cared less about characters.

Skyrim. I am not into the whole TES lore, but just the main story was weak and horrible. It is good for mods though.

Star Ocean: Til the End of Time. So campy the dialogue.

FF X-2. Fun mechanics, but really? Just really?

I can't think of another, but I am sure if I took out my PS2 library I could find something...
