There is a moment while watching the international trailer for Little Fockers (Spanish-subtitled, because why not) where you may think, "This looks tolerable. Hey, Robert De Niro and Ben Stiller aren't at odds anymore. That's good, maybe they're doing something different with this franchise." Then Stiller's son projectile-vomits in his face, and Stiller himself squirts blood on his entire family.
What else does this trailer tell us, besides that fact that there might be a very overzealous person in charge of practical effects who is not all that familiar with how liquids shoot out of actual human bodies? Not a lot, aside from the fact that Teri Polo and Blythe Danner still don't get above-the-title billing after three movies (yet Barbara Streisand and that interloper Jessica Alba get credit for their appearances). Oh, and Stiller and De Niro eventually scuttle their tenuous peace and start fighting again. Those boys, when will they ever learn, etc. etc.
VERDICT: I need a napkin.
