“Day 13” (** out of four) was a tepid suspense thriller about a young wiseguy (Alex MacNicoll) who meets a cute girl next door (Meyrick Murphy) but soon begins to suspect that her father (Martin Kove) is evil and he begins to snoop around and engage in surveillance until he finds out for sure. Reasonably well-made and MacNicoll is a winning actor but many find this all-too-similar to Shea Labeouf’s “Disturbia” which in itself was a derivation of “Rear Window.” Story also morphs into silly and hokey supernatural territory in its final third. Kove is well-cast but wasted as the neighbor.
