“2:Hrs” (*1/2 out of four) was a scattershot, silly teen adventure comedy set in Britain about a young mischief-maker (Harry Jarvis) and his friends (Ellla-Rae Smith and Alhaji Fofana) who stumble onto the invention of a mad scientist (Siobhan Redmond) and discovers he only has 2 hours left to live and tries to cram as much fun and adventure as possible in the next few hours. Likeable cast and energetic direction by D. James Newton can’t enliven a movie that’s pretty much dead to begin with. Young kids may like it but it’s hardly worth anyone else’s 2 hours.
