We're showing our age here, but we distinctly remember watching the original Flash TV series on Sky One many, many years ago. This new iteration sees Barry Allen (Grant Gustin) as a crime scene investigator who's bestowed with superhuman speed after a freak accident. The Flash has become a huge success in the States and is likely to do just as well on this side of the pond. The mid-season premiere episode sees a new vilain, The Nuclear Man, take front and centre whilst General Eiling (Clancy Brown from The Shawshank Redemption) return to Central City.
