Good Flash animation (now known as Adobe Animate), and the character designs are faithful to the original designs and it gets even better in Season 2 onwards.
Great voice acting. Tuffy's voice by Kath Soucie sounds really cute.
Despite being short, the theme song is a nice updated version of the original Tom and Jerry theme tune.
Tom & Jerry's dueling is still enjoyable to watch.
The Cat and Mouse Detective series is a very nice addition to the series, being a great mix of great slapstick, funny dialogue from the narrator, the use of Tom and Jerry's love-hate relationship, and taking the franchise to new directions.
The Witches' Cat and The Lab Mouse are really clever and open up new possibilities for storytelling.
New Memorable Supporting Characters such as Napoleon, Red Herring, Dollface, etc.
Many of MGM's other characters from the franchise such as Droopy, Butch the Irish Dog, The Wolf, George and Junior, and Screwy Squirrel return in the show.
The Flash animation, while good, is not really the best. It appears to be much more stiff with no outlines and restricted during Season 1. Thankfully as of Season 2 onwards, the animation quality has improved to be much looser and more true to the original shorts.
While most of the characters stay true to their original personalities, Spike the Bulldog has been rather flanderized, where he went from from a stereotypical bulldog who had a good side (as he would either help out Tom or Jerry whenever it was necessary) into a mean, short-tempered and unlikable jerk who beats up both Tom and Jerry.
It is revealed that Butch the Irish Dog is the twin brother of his previous name who is depicted as a clone in The Cat and Mouse Detective episode Double Dog Trouble. This could get very confusing and is a major plothole to the franchise as Tex Avery renamed the character from Spike to Butch in order to avoid confusion with Spike the Bulldog.
Speaking of confusion, Toots (the small, yellow female cat from The Mouse Comes to Dinner) is mistakenly named Toodles Galore by Darell Van Citters, but the actual Toodles (the slender, white female cat who first debuted in Springtime For Thomas) appears in one episode in Tap Cat.
Apparently, the animation change was because the series' director was not a fan of Season 1's animation style, so animator Rob Fendler was hired to improve its animation quality.
Additionally, episode segments run for 11-minutes in season 1, and 7-minutes for the rest of the series. This was done to prevent the segments from running too long.
Similar to how the direct-to-video movies Shiver Me Whiskers and A Nutcracker Tale were based off the TV series Tom and Jerry Tales, the 2014 TV special Santa's Little Helper was based off this 2014 series.
The series has received generally mixed to favorable reviews, with criticism primarily directed at the switch from traditional hand-drawn animation to Flash animation since the previous Tom and Jerry TV series, Tom and Jerry Tales, and the praise being primarily directed at the well-done Flash animation and its success at recapturing the spirit of the original shorts.
