I'm enjoying the show a lot. It's extremely lame that they stuck them in the 70s for three episodes (and did nothing with the time period except had Sarah dress in 70s cosplay), lame that they're going to hit up the 80s next for what will probably be just another fashion swap, I don't really understand why they so easily give up every time they run into Savage and just run off, and the Hawks are a drag.
But the rest of the cast is a lot of fun, especially Sarah, Cold, and Heatwave (doubly surprising since I thought he was awful on the Flash). I'd probably put it second to Flash but above Arrow this year. Doesn't make a whole lot of sense, and often feels it's wasting the potential in its premise, but this cast and the surprisingly impressive effects make the show for me.
