One moment that makes it all worthwhile
(Spoiler free)
Like a film or hate it, I always look for at least one line or scene or shot that shows true originality. In the case of Boo, it was the kid trying to shoot the lock off the door. To the best of my knowledge, that wasn't ripped off from anywhere and it's a scene that has been overdue for about fifty years. I doff my hat to whoever was responsible.
My opinion by the way - graded against the curve Boo is in the top 20% of the films shown on Sci-Fi Schiddy Scinema Scaturday. Don't try to compare it to a B theatrical release (like 13 Ghosts), compare it to Mansquito or Pterodactyl. If you're watching Sci-fi channel on a Saturday night, it's not like you don't deserve what you're getting.
