I was surprised how much fun this one was. It definitely felt like a throwback to the old 80s kid monster flicks like Monster Squad or Fright Night. Speaking of the kids ... I do kind of wish they had been a little younger than high schoolers. I think it would have made it all a bit more lighthearted and goofy.
But oh man ... I just couldn't get past Jack Black using his dopey fake accent for the ENTIRE movie. 5 star movie if they had cast Will Arnett in the role of R.L. Stine instead.
