It's getting late, so I'll keep things simple...
First, the film far surpassed my expectations. Not being weighed down by the need to make W jokes every few minutes allowed them to focus on being funny and it paid major dividends. If you've seen the first two, you know in general what is coming, along with a few interesting cameos.
Second, the 3D effects did what they were meant to do. Still the most skippable from any movie I've seen, which include post-prod converts.
Third, NPH is still the man.
And last. but not least, pancakes do indeed suck.
