The ep fully embraced the craziness of a comic book crossover and crammed a lot in!
t:
I thought they did a great job of establishing Vandal Savage as a force and the actor has a real presence about him, and the Hawks full debut was well done, getting them in place for LoT.
The banter and interactions between the two teams was a lot of fun, Barry's response to Malcolm's second appearance, Ollie and Felicity's exchange during the fight with the Ghosts, Thea's reaction to realizing they know The Flash, Cisco's one liners and exchanges with Felicity.
The action was also on point, the magnetic arrow against the Ghosts was neat, the fight between Vandal, Ollie, Barry and Thea at Ollie and Felicity's apartment was great, as was the Flash/Arrow vs. Hawkman sequence.
On the STAR Labs side of things it was cool seeing Caitlin and Harry progressing things together on the Zoom front, but that place is even less secure than the Arrow base, Patty is going to have to be in on things soon.
Looking forward to part 2.
