Plain old Boring!
I remember GET SMART with fondness and loved watching it with my dad in the 60's-early 70's, so I guess I was expecting too much from this film and I actually left the theater about 40 mins. in. It just was not funny. It tried hard with the gadgets, and quips from the TV show, but for me it just didn't connect at all. I'm not being critical, just honest.
