David Clark (Jason Sudeikis) has life sussed as he has no family, no wife and lives under the radar whilst making a nice living dealing drugs. That is until he gets robbed off all his drugs and money and so to clear his debt to Brad Gurdlinger (Ed Helms) has to go to Mexico to collect a smidge and a bit of drugs. In order to do this David persuades his neighbour Rose (Jennifer Aniston), a stripper, Casey (Emma Roberts) a street kid, and Kenny (Will Poulter), the naive kid downstairs, to masquerade as the Millers a family on an RV family holiday.
"We're the Millers" is like 3 movies squeezed in to one, combining the obvious road trip elements with a bit of the classic fake relationship storyline but smothered in the sort of comedy where swearing is part of the main arsenal. And to be honest "We're the Millers" is surprisingly entertaining as it flicks between all three so one minute we will have some thing close to tenderness as David's true feelings towards Rose emerge but then that is followed by something along the lines of Kenny ending up with a swollen testicle due to a tarantula bite or a scene where Rose and Casey teach Kenny to kiss. But then you get on top of that the usual road trip elements from vehicle trouble to being chased down by a Mexican drug lord.
The thing about "We're the Millers" is that none of it is that surprising especially with the tone of the comedy often being one of angry as we have the characters bickering and swearing at each other. Yet even when it is at its most stupid, such as an almost gratuitous stripper scene, it is still entertaining with each of the actors playing their parts well, especially Will Poulter who certainly had a field day with his role.
What this all boils down to is that "We're the Millers" is just some modern comedy fun which combines some familiar themes and gags with many of the funniest moments coming in the gag reel before the credits roll.
