The Flash is sometimes painfully bad in the details of the storylines, and the sub-plots. Some of the villains are really good, and some are lol-worthy. IOverall, the main arc is great, and Tom Cavanagh is fantastic. There are a lot of unexpected twists. It's quite a bi-polar TV show... but I'm still watching it. I too know nothing of the DC universe, so it's nice to not have things 'known' in advance.
