Arrow: 10 Greatest Episodes
4. The Brave And The Bold (Season 3 Episode 8)
There isn’t much to smile about in season 3, but Barry Allen and Team Flash never fail to amuse. The second of the CW’s original two-part crossover is one of the more fun hours of Arrow, and kind of the only time that metahumans on Arrow has worked.
Seeing Barry, Cisco and Caitlin struggle to cope with life inside the Arrow Cave, and Ollie and Diggle's attempts to keep the ever chipper trio from lightening up the place too much is priceless. Where the episode stands out, though, is in its action. Captain Boomerang is introduced to Star City, and his showdown with the Green Arrow, as well as Ollie's face off with a mind-controlled Flash, are some of the best choreographed scenes in the show's run.
