The big green babysitter is back, but the charm has evaporated. Cinephiles will enjoy some of the in-jokes (watching an awful play, one character cracks, “This is worse than Love Letters“). But then, if you’re a cinephile, why would you bother with this? Chris Miller and Raman Hui directed; with the voices of Mike Myers, Eddie Murphy, Cameron Diaz, and Antonio Banderas. PG, 92 min.
