I will start by saying that I have enjoyed many Adam Sandler movies and have found him to be a generally funny guy when I've seen him interviewed and when he was on Saturday Night Live.
I laughed gleefully through Anger Management, Mr. Deeds, Billy Madison, 50 First Dates, and Happy Gilmore. Funny People and Just Go With It were awesome movies! I was brought to tears in Sandler's emotional portrayal in Reign Over Me.
I have great respect for the man as a comedian and actor. But Jack and Jill is abysmal. The "jokes" are not only bizarrely misplaced - THEY ARE NOT FUNNY. I did not hear a single laugh, not even a slight giggle from any audience member in the theater. In fact, almost 1/3 of them walked out before it was over. Those who stayed, openly derided the flick as we all exited the theater in utter disgust and sadness.
I don't know why Al Pacino was in this movie, his acting made it seem like he was forced at gun point to do this movie. Nick Swardson and Tim Meadows are way too funny to be in such a disaster. Especially given Swardson's stellar performance in Just Go With It.
This movie is not a flop, its not an "oops", its not a mistake - it's a career ending pile of trash. A career ender that started with Sandler's god awful "Grown Ups" and climaxes with this revolting hunk of garbage.
Sorry Adam, it's over.
