Why Him? is perhaps a little over-stretched.
Why Him? is built around a very stock comedy template. A hard-working old-fashioned father finds himself at odds with his daughter’s new boyfriend, leading to a clash of competing masculine egos. The most innovative aspect of Why Him? is the decision to filter this standard comedy plot through two more filters. Why Him? is simultaneously a raunchy R-rated comedy full of profanity and bodily-function jokes. It is also framed as a Christmas comedy, as much as a comedy set in and around Los Angeles can seem like a Christmas comedy.
These are hardly the boldest of innovations. Why Him? is a paper-thin comedy that is somehow stretched out to run over one hour and fifty minutes. There are any number of gags that work and a solid cast that never rises to exceptional, but the fact is that all of these elements overstay their welcome by at least a good twenty minutes. It is telling that one of the biggest issues with Why Him? is repetition, where the movie attempts to spin out slight jokes that prompt a knowing smile into running gags that exhaust all good will.
Ironically enough, given the title, Why Him? never makes a compelling case for its own scale and length.
