Grant Gustin Calls 'The Flash' Season Finale 'One Of the Most Exciting' Ever

Grant Gustin has given the highest stamp of approval on tonight’s The Flash season finale.

Speaking with EW, the 28-year-old actor says it will be “one of the most exciting” finales the show has ever done.

Grant adds that it’s also “one of the most dark and confusing. When I say confusing, it’s more like, in Flash world you just desperately want to know, ‘What does this mean?’ The first one gets you really excited about what’s to come, then the second one probably is going to make your stomach hurt, and want the next season immediately.”

The Flash airs TONIGHT, May 22nd @ 8PM ET/PT on The CW.
