“Agents of S.H.I.E.L.D” just had by far the best midseason finale of any fall show. There, I said it. The level of awesomeness on display here was beyond compare. Oh, and it also just happened to unlock a previously untapped side of the Marvel Universe that has the potential to impact just about every upcoming Marvel movie. Pretty cool for a show that too many impatient people left for dead last season, huh?
