Scoob!
Eh. It was okay I guess. The animation was pretty darn good! Lots of references to Hanna Barbara littered throughout the film. (I was hoping for some more cameos from Hanna Barbara's library though.)
Dick Dastardly was a great villain. He stole the show, imo. (Kinda reminded me of Dr. Robotnik with that giant ship of his and his army of robots.)
Blue Falcon's new design was pretty slick, but Dynomutt came off as a bit of a jerk in this. I didn't really like him. His random human sidekick was pretty bland too. She didn't really have any personality, she just existed to fix Falcon's mistakes.
Shaggy's new voice was alright, I guess. It was no Matthew Lillard, but ok.
No Avengers style post credit scene? Total missed oppourtunity for a Jetsons or Flintstones cameo!
I give it a 6/10. I'd like to see a sequel with more Hanna Barbara characters.
