When I was younger I used to watch Scooby-Doo. Always trying to track the bad guy as I'm sure it is a murder mystery cartoon...or if not murder, people go missing, no? I really can't remember and really don't care at this point. But I remember it used to be fun especially when they introduced Scrappy-Doo, the tiny version of scooby that loved to fight. However, once I was told that Scooby-Doo and the gang was a bunch of Hippy druggies and that only Shaggy talks to Scooby and Scooby talks back to Shaggy (kinda like Stu and his Mum in Family Guy, that kinda thing, sorta) and they understand each other because Shaggy is constantly high. I had no idea they were hippies when I was watching it as a young boy. Plus, you don't see shaggy on drugs or taking them (Kids TV), but he seems to be clearly on it. It was at that moment, my mind was blown. I cannot validate this and maybe this information is wrong, but I've never cared to try and find out if it were true or not, or if it made sense.
As for this movie trailer, it isn't for me and I really don't care for an origin story of Shaggy and Scooby. They are not aiming this film at me as I am NOT the demographic and it doesn't seem like a movie as clever as a Disney Pixar's Toy Story or Incredibles for it to also appeal to adults, ie myself, so I have nothing to really say about it as I wasn't entertained by it. What I did like about it though, was the updated animation and how the characters were drawn, I really liked that. The drawings were very modern but they kept the aesthetic which I loved. Other than that, this needs to amaze me to be interested and I really don't see that happening.
Directed by Tony Cervone and starring Kiersey Clemons, Zac Efron, Will Forte, Jason Isaacs, Ken Jeong & Tracy Morgan
