Since I'm being honest(see post below "Iron Man 2"), I will tell you i AM very excited for the 4th Shrek.  All of them have been great, and even if I didn't have kids I would at least rent them.  I've enjoyed most of the Pixar and Dreamworks animated films.  This one's gonna be in 3D, which means if i can get away without telling my kids, I'll take them to the regular 2D one over at the east side Marcus and save a few bucks.
