So I am a couple of episodes in on Season 4 now. The first episode felt really wandering, but I think the idea was to sort of set up some of the secondary folks for the season.
I kind of don't like so far how Wallace and Mac are basically non existent. I guess it makes sense that Veronica isn't constantly paling around with friends now that she is an adult.
There is definitely a bit more sex and swearing than the old show, since it's Hulu now, but they didn't go overboard with it.
Holy crap that cold open return of Dick. "Oh hey, is that Dick? He looks funny with that beard... WTF?! Oh... Hah, that's great ..." Honestly, he doesn't DO much, but I have always found Dick kind of interesting. He is almost always close to "the killer" for the season arcs in some way but never involved or even aware. He's kind of a jerk, but it's more in a clueless way as he kind of feels like he means well. Also when rewatching, it was funny seeing him as a nobody background character at first. I remember saying "Hey, Dick finally got a name" after he had showed up like a dozen times unnamed. It kind of reminds me of Santana and Brittany in Glee, who were literally just background characters to Quinn in Season 1, then by the end were basically the main cast stars.
I have no idea where things are going to go. I kind of wonder how the Cartel (or whatever) guys will play into this, since they seem to be working towards the same goal of finding the bomber, just, considerably more violent about it.
