I wasn't impressed by the trailers and it's no surprise to see the game being slammed by many reviewers. The series has been going downhill since the original game. And the trailer with the nuns was simply ridiculous - comically bad but not in a deliberate way.
Here are some juicy quotes:
"Absolution isn’t a complete failure" -
Rock, Paper, Shotgun"Absolution is not worth buying" -
PC Gamer"The PC version, from developer Nixxes, has a number of bugs that have yet to be fixed a day before launch" -
Joystiq"It's difficult to tell what IO was trying to do with the characters: were they meant to be intentionally funny, or are they simply poorly designed?" -
Shacknews
"The price of freedom is eternal vigilance."
