Went to the theatre to see Shrek 3 with Tole, his better half and the sprogs.
Kiddos loved it.
Personally, I loved Shrek 2, and the first movie tickled my funny bone, too.
This one ... fifteen minutes into the movie and I'm rooting for Prince Charming. The charm of the Shrek franchise is the sly stuff aimed at the adults in the audience -- well, I don't know if someone complained, or what, but #3 lacks the wink-and-a-nod at the grown-ups.
Without that, Shrek 3 is just a ponderous, stodgy, completely predictable children's tale.
Plus, it kind of felt like Mike Myers phoned in his performance -- probably figured out that his money ride is coming to an end.
If you have little ones, go see it. Otherwise, rent a DVD copy of Flushed Away and save yourself the $7 matinee price.
