Dead Island most definitely did not suck; it was a total blast, and I played it through twice back to back. Sure, the gameplay wasn't directly related to what was in the trailer, but that's true for most games. To it's credit, the trailer was brilliant (and disturbing). Even better though is the 'literal' version of the trailer, which was downright hilarious. "Never give a zombie girl a piggy back ride" - should be one of the rules of Zombieland.
