I don't want to waste any more time than I already have on this turd, so I'll make this brief, and I'm not even going to spell-check it.
This movie should never have been made. It is a complete waste of Ben Stiller, and an utter disappointment coming from writer/director Noah Baumbauch, who so impressed this critic back in 2005 with The Squid and The Whale (my #1 movie that year).
Two depressed, social misfits sharing long, awkward conversations should not a movie make. The only funny bits were shown in the trailer and made this film seem like a comedy. Which it is not.
Avoid it. You're welcome. Skip it!
