Piranha (2010)

The problem with this exploitation remake/homage to “Piranha” (1978) isn’t the gratuitous blood and breasts. The problem is execution. Richard Dreyfus’ cameo — and eventual death — in the first scene hints at 90 minutes of fun, then the movie disappoints.

The Karate Kid (1984)

John Avildsen (“Rocky”) directs another underdog story — a real crowd-pleaser that honors karate and friendship. The bullied teenager (Ralph Macchio) is a little too precious, but Pat Morita’s Oscar-nominated turn as Mr. Miyagi gives the film its heart.
