"Everybody was Kung Fu Fightiiiiiiiiing/Those kids were fast as lightniiiiiing..."
Doesn't that count? That is, isn't the entire movie a single pop culture reference (specifically, a reference to this disco song from the 70's)? Further, the movie even ADMITS it; it features a cover version of the song in question.
In any case, regarding the "anti-Dreamworks bias" in question, can you blame them? Ever since the beginning of the "Shrek era", there movies have only been "family entertainment" simply because it's convenient for them, and thus figure it would be convenient for the parents, thus, their movies are more for the parents then they are for all of the family. This is why I don't bother with any of their post-Shrek movies; Pixar is Pixar, and Dreamworks is Dreamworks. In other words, my dislike for Dreamworks has nothing to do with any comparisons, because in the end, it's the material itself that makes them..."unlikeable" (for lack of a better term). Personally, "I like to move it, move it", but that doesn't mean I'm stupid enough to think that the movie it was featured in (hint: it's also the name of an actual African country) was the origin of it; I know it's a dance hall song from the mid (early?)-90's even if they don't think I do.
As for Kung Fu Panda, the thing is, even if it doesn't rely more on pop-culture references (again, like their other movies do), it might as well be the case where Dreamworks is concerned. Really, G rating? PG rating? It makes no difference. Claiming that a movie is a "family" movie, when it's more about giving the grand/parents something to entertain their grand/sons/daughters with, is not family entertainment, it's both sarcasm and hypocrisy, and is an insult to anyone's intelligence...even Dreamworks'. Unless Dreamworks actually (with all due respect to them) gets a clue, and realizes this, I will never watch any of their post Shrek movies.
*(Chicken Run doesn't even count anyway since it was a 3rd-party production to begin with; OTOH, Flushed Away was a co-pro, and it's not that good, so that does count).
EDIT: Oh yeah, I forgot, isn't Kung Fu Panda also a single reference to those bad kung fu movies from the 70's and 80's?
