I've watched this episode 3 times now. I really like it. I liked the comics and the animated series, but I didn't love the last live action version. This is by far, the best character development of any iteration of The Tick. Arthur's back store is excellent, and Griffin Newman plays it brilliantly. Peter Serafinowicz's acting as The Tick is a little rough, but he's a good actor and I have no doubt he'll pull it off. Plus with Patrick Warburton as a producer (as opposed to playing The Tick like he did the last time) I'm sure he'll coach Peter along.
To me, this is more representative of the comics, which could be darker than the animated series. Arthur's back story is definitely darker and it seems that Arthur's story line is going to carry the series forward while The Tick may be "the sidekick" to the story. I really hope Amazon picks this up, I can't wait to see where Ben Edlund takes it from here.
