Ok it is not nearly as funny as the 1st and 2nd ones but it was entertaining and fun for the whole family. It has very funny moments, I think the interaction between DeNiro & Stiller has become predictable which takes some of the edge off the comedy. Stiller is trying to please his Father In Law and gets himself into situations that are funny but you kind of know what is coming. DeNiro is a bit more of a buffoon in this one which I think detracted from his charachter in the series and Hoffman and Streisand were pretty much cameo after thoughts in this one.
