Ferrell (left), departing from his usual habits, resists getting naked in this overblown special-effects comedy—though he does scamper about in shorts and, later, his undies. But that's not the scary part. That part would be the rampaging dinosaurs which chase after scientist Rick Marshall (Ferrell) and his time-traveling buddies after they end up in a land where, as Marshall puts it, "the past, present and future are all mashed up." Mashed up perfectly describes Lost, which can't decide if it's a wild and crazy comedy, a laid-back spoof or a full-on Jurassic Park Jr. There are funny lines and bits, but mostly this is a long slog.
