The first handful of episodes of season 1 are mostly unremarkable but decent, if a little shaky here and there
Then they drop this bomb for the Christmas episode and it's ALL GAS NO FUCKING BRAKES for the entire rest of the season. Absolutely insane stretch of superhero TV
The reveal that Harrison Wells was actually the Reverse-Flash was genuinely insane.
you spend the entire season watching this man guide Barry, train him, and help him become the Flash
then you slowly realize that the person helping Barry become a hero is also the person responsible for destroying his life
Season 1 of The Flash really had something special.
