“The Mouse Trap” (*1/2 out of four) was a one-note horror show about a girl (Sophie McIntosh) celebrating her 21st birthday at an amusement park with friends (Callum Sywyk, Mireille Gagne, and others) when a homicidal slasher dressed as Mickey Mouse (!) is on the prowl and killing everyone one-by-one. This is what audiences get for making the “Winnie The Pooh” horror films a hit. Opening title sequence is pretty flippant and amusing but rest is standard stalk-and-slash fare. What’s next? Donald Duck as a strangler? Kermit The Frog as a kidnapper?
