What a treat! As a big fan of Scott Pilgrim (the comics, though I also liked the movie in its own right), it ended up surpassing my expectations, especially around episodes 3-6. The animation is really pretty, and the more ensemble style the story takes is perfect for what it's telling.
I want to make one thing clear though: Scott Pilgrim Takes Off is not the original story, and you'll probably enjoy it better if you keep an open mind about where it's taking you. The trailer for Takes Off made it seem like a remake, and that was a mistake to me. A lot of people who have already seen the original might not bother watching a remake (which this isn't), while a lot of people who have not seen the original might expect Takes Off to stand on its own.
I'm not sure it fully does! I see it more as like... a B-Side to the original.
And damn are these new tracks worth it. Ramona shines in this show, but the real surprise for me was Matthew Patel?? He's so funny in this, on top of getting character development that he never got to have in the original.
The show's just ton of fun! And through revisiting a story that's affected the author as much as the original has, it adds some meta elements that don't feel out of place or overstay their welcome.
It may have stumbled a bit for me at the very end when trying to wrap everything up, but the journey was more than worth it!
