“Let Us In” (** out of four) was a half-baked sci/fi hodgepodge about a small-town girl (Mackenzie Moss) who begins to investigate the sudden disappearance of several other friends in her area and begins to realize that there may be other and larger sinister forces at play and turns to a local cultist (Tobin Bell) for help. Well-intentioned and well-acted but never escapes the feeling of warmed-over Jim Henson, Steven Spielberg, and Ron Howard all ground up in a mild blender. Bell seems to be doing outtakes of Jigsaw all over again and is in film very briefly.
