How can you say that? The developers could have turned TPM into a good game. A bad movie doesn't make a bad game. A good movie doesn't make a good game either. GoldenEye, for example, was a sub-par Bond movie, but it became the best console fighter for a looong time.
LucasArts in the past two years has been having trouble. Most of their old programmers and designers left. They lost a lot of talent and experience. A big problem was churning out a ton of Episode 1 games. Combined with absolutely no communication with its fans, LucasArts was begging for trouble.
But I think they're on the right track now.
