The Watch pits a coalition of concerned residents against a full-blown alien invasion in the fictional idyll of Glenview, Ohio.

It’s a preposterous premise, ripe with humorous potential.

Unfortunately, screenwriters Jared Stern, Seth Rogen and Evan Goldberg throw a relationship sex comedy and a goofy buddy movie into the mix and this pot pourri of competing genres creates an almighty stink.

Director Akiva Schaffer is poorly equipped to find method in the script’s madness and his film implodes early on.
