I may be one of the only people watching at this point, but episode three was actually pretty good. Flash's best friend Nick is bitten by a deadly insect from Mongo, and Flash must obtain an antidote from an Amazon-like society. Meanwhile, Dale must slow the toxin's effect on Nick by stressing him out at his brother's wedding.
This episode unveiled a title theme (not a cover of Queen) and credits that didn't match faces to names (ala Season One of Bones). Flash's willingness to sacrifice himself for others feels homespun and genuine. I liked the higher stakes, but cutting between Mongo and Earth still makes for a choppy pace.
