I've been pretty excited to watch this show since I first heard about it several months ago. It has MMA (which I've been into off and on for years) and Frank Grillo (who I'll watch in pretty much anything, including Purge: Anarchy in the theater).
The hottness of Mr. Punisher-Light aside, I was pretty pleased with how good this was. I was able to get a good sense of the plot and where it would most likely be going within the first episode. Money troubles, Nate's injury and Ryan's comeback are probably going to be the main things for this first season.
I also liked that of the main characters, none were all good or bad. Alvey is a great trainer, but seems to have a pretty screwed up past. Jay is a druggy, but really cares about his little brother. Ryan massively self destructed back in the day, but seems to be genuinely trying to work his way back.
I could stand to have more women in the show though, Lisa is fine (aside from the hideous shirts they are sticking her in), but the only other women right now is Jay and Nate's mom who at least is pretty much a non-entity, at this point.
When Alvey beat the shit out of the gang bangers in the very beginning, I figured it was just a way to quickly show how much of a bad-ass he is, but when they showed up again, I knew things weren't going to go well. I did not think that they were going put Nate in the hospital though.
On a final note, I thought it was pretty funny that were went straight for the modesty towel at the weigh in without going normal first. Apparently it was a good idea, though, as he came in right at the line.
