Wrecker seems too much like Zeb. I thought that the shootout scene lacked believability because a couple of clones fought off a dozen stormtroopers. However, the show did hit a couple of important emotional notes, but none of it was earth-shattering.
The first episode was so good that I watched it a couple of times and I will likely watch it again. This one not so much. It was like watching the Star Trek The Next Generation Episode "Family", where the episode hit a couple of emotional notes and not much else.
