I beat it the other day, and the story is leagues better the Boarderlands 1. The only real Issue I had with this game is the last area kills any momentum the plot had built up, and it's rather unsatisfying. Still a great game though.
The exact same thing happened in Borderlands 1 though when you fight those Vault robot guards & Crimson lance soldiers at the same time. I still can't wait to pick this up next weekend
