“Gilmore Girls” is back, but much has changed since Lorelai and Rory were last on our screens. In 2007, you had to be in front of your TV at 8 p.m. every Tuesday, but viewers do not have to be bound to their TV schedules anymore. “Gilmore Girls: A Year in the Life” is exclusive to Netflix, so it’ll be available whenever you want to watch it. However, some will want to be first in line to see it.
