I kind of feel like Velma looses some of her original charm if they purposely pick an actress that looks like a model to play her, and then have her with make-up and perfectly plucked eyebrows throughout the movie, along with substantial cleavage at times. Not every character needs to be a model in live action, imo. Daphne has that covered.
I mean the original Velma was all like:
The illustrators clearly went with two different styles for Daphne and Velma, including lip color for Daphne but not Velma, but in live-action they basically take two actresses that look like Daphne and with make up on, and give one the hairstyle of Velma.
I dunno I'm not exactly a huge Scooby Doo fan so maybe I missed something.
