If only for that voice. The Blacklist won’t run forever and watching Boston Legal only gets you so far.
A bit of a snafu happened when the first trailer for Avengers: Age of Ultron leaked online a week ahead of its debut on Agents of S.H.I.E.L.D. Instead of trying to find and delete it, Marvel did the best thing possible, they went ahead and released the official one and blamed Hydra for the leak.
Even Marvel fails upward.
Will the trailer make your life better? Maybe not, but it can definitely help with certain things: wife leaving, sinus problems, indigestion.
