The summer blockbuster season is going to be a jolt for fans of science fiction if this trailer is any indication. Michael Bey has returned to direct Transformers 4: Age of Extinction.  No, Shia LeBeouf will not return to annoy half the sci-fi nerd world with his chronic overacting. Replaced by Mark Wahlberg running from Decepticons, the plotline picks up the action four years after the events that transpired in the prior installment of the franchise.  Very little has been revealed about the plot, but the trailer below is filled with all kinds of delightful sci-fi fireworks. See for yourself.
