Games with the worst/loosest gameplay-theme connection?

Seeing the many posts here about thematic games, I thought it would be fun to think about the opposite. What have been some games that have turned you off due to their tenuous connections between theme and gameplay?

I'll go first - I just couldn't get myself to enjoy one of the latest euro games 'Earth' because of how dry the theme was and how loose the thematic connection felt. It felt like I was just converting cubes into different kinds of cubes, and the theme never really came through anywhere.

Would love to hear more opinions.
