Well you have to be an Amazon Prime member, I believe - but the first month is free so you can subscribe and then cancel any time within that 30 day period with no penalty.
The pilot is free, since they want people to watch their pilots and give feedback on which ones they want picked up. I just watched the whole episode. It's pretty good, though definitely darker than previous versions. It's not even clear whether The Tick is a real person or Arthur's hallucination, though I doubt they'll go the
Fight Club/Mr. Robot route.
I have not seen the clips you refer to.
One was the Tick attacking the bad guys, ending with the explosion. The other was the Tick/Arthur scene in Arthur's apartment from the "secret lever" bit with the coatrack through the reveal of the flying suit.
On the whole, Serafinowicz did a pretty good job. Once I got used to his approach, it worked pretty well. I do think his vocal performance was more effective than his physical performance, though. He doesn't quite have the jawline for The Tick, and his expressions didn't convey the character as well as his voice did. Being in the stiff costume didn't help; maybe they'll make the neck a little more flexible in the future.
The production values were pretty good, and seeing actual, big superhero action and effects was a vast improvement over the previous live-action series that was basically just
Seinfeld in weird costumes. I note the costume design was by Colleen Atwood, who also did the Flash and Supergirl costumes. I'm still not sold on the Tick's new, more exoskeletal look; it does fit the name better, but part of what was fun about the original design was that he
didn't look anything like a tick. (As made clear in "The Tick vs. The Tick," where he went up against a namesake hero whose costume actually did resemble a tick.) And Arthur's high-tech, bulletproof flying suit is kinda neat, but I liked the frumpy, homemade look of his original Mothman costume.
I tried to take Amazon's survey and give my feedback for the show, but I got fed up when it just kept going and going and asking questions I couldn't adequately answer. (How the hell can I pick out my three favorite shows of all time, and what business is it of theirs anyway?) They should've kept it brief or made the questions optional -- they'd get better response.
