This show is great for a first watch because it's like a magic show for people who love adult superhero stuff. But the second time around, you figure out the biggest trick on your own and realize they only wow the audience once per episode with a memorable scene (with the exception of the pilot and finale, which need to have a few more memorable scenes). A good amount of these scenes don't advance the plot at all, but are memorable for their shock value. These scenes are enjoyable and they serve their purpose of keeping the viewer interested, but the rest of the show is just a set of pretty dull buildups to these intense or funny scenes, which is why I think a magic show is a good comparison.
