I don't HATE hate it, but for the most part yeah I don't like it. As the guy said in that quote, the whole "really, water kills them?" is a groaner of epic proportions that really ruins the whole movie. I mean the entire atmosphere of the earth is water. If it really was holy water, one would expect this point would be expressed in a lot less subtle manner. Also, during M Night Shymalallaldnladingdong's cameo, he tells Mel Gibson he's going to a lake because "they don't like water".
I did enjoy some of the predeterminism. ie: 'Swing away, Merrill' and then we get to see Joaquin Phoenix go to town on an alien with a baseball bat. That was pretty sweet.
