The last Scooby Doo TV show, "Be Cool, Scooby Doo", was poorly received and really lowered the reputation of the SD series, even though I personally think it isn't that bad and most of its flaws stemmed from behind the scenes drama. This show, "Scooby Doo and Guess Who", is a vast improvement over that series and is a great throwback to the classic show.
The show's animation is really crisp and has a vibrant color palette, but it also manages to capture the look and feel of a typical Hanna-Barbera show from the 60s. It even uses classic tactics such as the "wheel o' feet", and uses stock sound effects from the Hanna-Barbera library. It also references other Hanna-Barbera shows such as Magilla Gorilla, Speed Buggy, and the Funky Phantom. Unlike, BCSD, which tried to be comedy-focused, SDAGW focuses more on the story and characters, as well as the guest stars, and restores the characters back to their original personalities.
Speaking of the guest stars, the show usually does a really good job of inserting the stars into the story, and they work well off of the Scooby gang. They all seem like they're having the time of their life. However, sometimes they're underutilized. Like in the Abraham Lincoln episode, where he only appears for a few minutes, and most of the attention is on the Funky Phantom characters. My personal favorite stars that appeared were Wanda Sykes, Wonder Woman, Batman and Weird Al. I definitely recommend their episodes.
If you miss the classic Scooby Doo, this show is for you. Especially if you like The New Scooby Doo movies which this show is similar to.
