Flash is great. And it has good SFX, most of the time. Plus, so far, we're getting things like Reverse Flash, Gorilla Grodd, and Firestorm. So that's rad.
Though you should know that, as a spin-off, the Flash exists in the same universe as Arrow. Barry Allen was introduced in the second season of Arrow (episodes 2.07-2.08), which was meant to serve as a "backdoor" pilot. And Olive Queen appears in Flash's pilot episode. There was also a crossover event, in which the Flash gang went to Starling City (in Arrow), and where Team Arrow went to Central (in Flash), so as to help each other out. The showrunners have stated that there will be a crossover episode in every season, ideally. Which is good news, since those crossovers were great.
So keep these things in mind if you're going to watch Flash.
Here's a series trailer.
I think Agent Carter is one of the better offerings the MCU has put out so far. Definitely worth watching, and with eight episodes, there's less of a commitment (and the plot doesn't dawdle). Plus, there's some Howard Stark in there (alongside Jarvis, the namesake of J.A.R.V.I.S.).
Maybe eventually. I'm in no hurry right now. Taking on another show would be a bit much. Plus, other shows are coming back in the next couple of months (foremost among them Orphan Black and Game of Thrones), so that should keep me busy, watch-wise.
TWD is indeed hit or miss. What it does well is atmosphere, and a sense of things going to hell. But things like pacing and character are often weak links in the chain.
I promised someone I would eventually catch up, so I intend to do so. But TWD is certainly not my favourite show.
What's crazier is that, according to the showrunners, they have plans for story up to 10-11 seasons. Yet the world's status quo can't possibly change by their own admission -- according to them, we'll never really know how or why the outbreak started, nor will we ever find a cure. So far, it's been a rinse-repeat cycle of finding some kind of shelter, trying to make a life there, things going to hell, then going back on the road in search of new shelter.
All of these factors don't lend themselves to a sustainable paradigm. Narrative scenarios are limited. People can either be killed off, grieve the loss of the dead, lament their situation, or become more and more ruthless. Only so many themes and points you can explore.
It seems more than enough for many, given the show's success. My brother is a huge TWD nut. I'm just less enthused about it, especially since there are so many shows of higher caliber available in our age of information (and streaming).
