When people sit down to make movies, they don't say "Let's stink up the joint." It doesn't matter if they don't say it, though, because more often than that they crap the toaster. Masterminds aims for middling humor and falls short.
The plan was simple: dumbass David Ghantt (Galifianakis) is to use his armoured car job to hijack millions of dollars. Then he runs to Mexico and hides out. Soon his lady love (Wiig) follows, and they live the big life after the man with the plan (Wilson) sends them their cut of the cash. Then it all goes to hell.
When the Berlin school began developing Gestalt theories of psychology, they did not reckon on so many right pieces creating such a wrong whole. The acting is solid with Galifianakis and Wiig pulling off convincing dumbass yet lovestruck roles. Even Owen Wilson and Jason Sudeikis come off as menacing evil doers. The plot meanders but is pretty straight forward. Moments come that are hilarious, I remember laughing, but none of them come to mind now.
In my capacity as a guy who watches movies and then pretends to give and honest opinion, I can't recommend you watch this. I can not say to log into Netflix, now $9.99, and find for "Masterminds" using their simplified search feature. Netflix, for when you want to watch something on your television through the internet.
