Strong outing for Fringe, which aired a new episode tonight for the first time in many weeks. John Noble, the Australian actor who plays Dr. Walter Bishop, showed some serious acting chops in this particular entry, set in the 1980s. The character actually did look 25 years younger--no doubt with the help of make-up and perhaps some digital effects, but Noble deserves a great deal of credit (if not an Emmy nomination, at least) for his excellent work.
