“Spirit Halloween: The Movie” (** out of four) was a fitfully engaging kids horror comedy about four friends (Donovan Colan, Jaiden J. Smith, Dylan Martin Frankel, Marissa Reyes) who spend Halloween locked inside the title store in a deserted strip mall but soon find out that they are going to have to use all their strength and horror-movie knowledge to survive. Thoroughly watchable movie aimed squarely at kids and hardcore consumers of the Spirit Halloween store but too bland for most others. Christopher Lloyd has a small but key role as a creepy villain.
