The opening act was painfully clunky and rushed, but they had a lot to establish in one episode. Things really came together once they made the first time jump. Some aspects are super cheesy, but it came together for me at the end. Once Rip came clean and they decided to become Legends, I started digging it.
Heat Wave and Captain Cold are so over the top that I can't even hate on it. Very rarely does stuff like that work, but they're the definition of being so cheesy that they're good.
I also like Jefferson way more than what we got in the Flash episode he premiered. His chemistry with Stein worked better here, and he had a good emotional beat.
I hope they continue with Cold, Heat Wave, and White Canary just being troublemakers. The "lets get weird in the 70s" scene was probably my favorite part.
The Hawk stuff is still just terrible. During the Flash/Arrow crossover, I was actually shocked by how much I liked Hawkman after expecting to hate him. I take that all back. Their interactions and Egypt storyline are like a really bad fantasy show from the 90s.
