Before the release:
I never watched it as a kid, and only binged it late in high school because I had been catching up on what I missed with Darkwing Duck. Not sure about the adult voices or David Tennant as Scrooge.
After the release:
The voices have grown on me, especially Scrooge. And the humor is on the same level as on Gravity Falls and Star Vs. Especially in the inflection of the way lines are spoken. Which can even be read with the Headless ManHorse.
"A head! I'm no longer a freak! Thank you!"
And everything Launchpad says. "Yes sir, random kid I just met!"
This is kind of my ideal on how a modern TMNT following the FW series footsteps should be. Taking itself a little more seriously while also embracing the silliness of the original.
