Innocent, forgettable, and funny enough.
This is a rare time when I don't agree with the general consensus on a movie. I was semi-apprehensive going into this because while I loved Bridesmaids and The Heat, Identity Thief was one of the worst movies of 2013. This isn't groundbreaking or generally rewatchable, but it's a nice, fun, forgettable, mild surprise. I laughed a bit and giggled a fair amount, and the cast elevates the material. The script isn't that good; there's barely a plot, but there are some solid jokes that Melissa McCarthy and Susan Sarandon help with. Mark Duplass is a nice addition as well, and there are some fun minor roles. The two leads have good chemistry, and while they aren't a match made in heaven or anything, they get the job done and are nice to watch. The pacing is fine despite the ending being about five minutes too long, and the jokes aren't mean-spirited or needlessly vulgar like Identity Thief or A Million Ways to Die in the West. I just don't know why they couldn't just make Sarandon be McCarthy's mother, since she's 23 years older than her and it's near-biologically impossible for them to be grandmother and granddaughter. I had a pleasant time, and even though the script is very loose, I had a bit of fun for 96 minutes. 6.8/10, okay, one thumb (barely) up, (barely) above average, etc.
