Interesting. I just blew through DD S3 a lot faster than I planned to, and was considering using the extra time to try The Punisher, which I'd originally considered to be a "maybe" after finishing JJ. Without getting too spoilery, anything in particular that really turned you off the show?
I didn't have a problem with season 1 -- at least, no more than I had with the basic concept of doing a Punisher series in the first place. That season was a pretty interesting exploration of PTSD and recovery, and it managed to portray Frank Castle in a way that didn't glorify his actions, that explored the moral questions his violence raised, and that ended on a fairly positive note. The problem with season 2 is that it undoes all that in the name of perpetuating the Punisher formula, something that's rendered even more gratuitous by the cancellation of the series. The main storyline feels like an afterthought, a rehash of plot and character threads already resolved in season 1, and it's hard to see what the point of it is. And it's packed together with a completely unconnected new storyline that jostles for the spotlight with the other one and doesn't have enough room to get adequately fleshed out. Basically season 2 did exactly what I feared it would do, invalidating what worked about season 1. Jon Bernthal still does some terrific acting, but he's playing a more one-note version of the character this time. It would've been better if season 1 had been the end of Castle's story.
