Alright, I got a few things to go through here.
First of all, I loved it, a whole lot, so much that I think I watched it too soon in the Halloween month - closer to the end would've been better, a time for when I leave the better movies, usually a Rob Zombie film or a new Scream (this year it's Scream 6 obviously) - because Totally Killer is just the right kind of movie for this: it's got lots of great songs, it's fun, and kinda gave me a feeling of watching the first Scream - as close as that can happen now, 27 years later anyway - and I believe that's the biggest compliment I can give!
But it is very forcefully 'diverse' - we got all primary 'necessary' races among main friends: black, hispanic, and asian, and the only missing 'element' was a gay couple, I thought, till they snuck that in at the very end. I laughed out loud, it's so obviously 'by the book' now, like checking off a list.
Somewhat nagging might seem Shipka's character's constant mentions and attempts at correction of 80s 'inappropriate' behavior, but I understand that's probably needed for 'modern audiences', or younger part of it, to pinpoint the difference. Although I think people would notice everything themselves, otherwise it's like a bad unnecessary voice over.
The ending 'twist' isn't very believable either, but honestly I had a lot of fun watching the whole thing, and don't really want to pick it apart. Basically I think one can hate this, or love it, depending on what state of mind they watch it in. It's certainly a product of this time, with a more judging look at the 80's, than movies from the 90s or even 00's had, but it's still one of the best things I've seen this year, for my taste, and certainly in this genre.
P.S. When did Lochlyn Munro, crazy fun guy from Dead Man on Campus, and A Night at the Roxbury, Screwed, and others, became a Dad... man I must be getting old.
Love Julie Bowen too. *Sigh*
