I just finished watching the first episode of Guess Who?, and I must say I was pleasantly surprised. The episode definitely goes back to the roots of classic Scooby, even down to the retro feel of the background music and sound effects at times.
Chris Paul seemed like a good guest star, and the vibe of this episode sort of reminded me of the Wilt Chamberlain (another basketball player) episode from Goober and the Ghost Chasers. Paul didn't overshadow the gang at all.
There were definitely some good bits in there, like the classic Shaggy/Scooby trick the monster gag, the Scooby Dooby Doors sequence among other humorous things such as Chris Paul not being able to get the ball in the hole at the end.
I didn't really like the intro though. It felt like too much of a rip-off of the Scooby-Doo, Where Are You? theme song (it's even credited as such in the end credits). I don't mind them trying to reference the classic theme song, but I would have preferred something original.
Though this was a small criticism, the bit at the end bugged me where the announcer said the cops recovered all the missing people. This was within like a few moments of gang capturing the swamp monster, and some of those people were just captured minutes before. I definitely get that they were trying to wrap things up, but the whole "Everyone captured by the swamp monster was found by the police, somehow within 5 seconds of the culprit being arrested!" felt a bit cringey. It seems like they were trying to cram everything in too quickly at the end.
Other than these minor criticisms, I'm really loving the new series and I'm definitely looking forward to next week's episode!
