I did take some time off of ROTJ and it hasn't regained any magic. If anything, it lost more. You gotta remember that this is comparing now to how we felt about it as children. To me, ANH and ESB gained more magic as I got older. ROTJ still lost it.
Oddly, I, too, am on Braveheart sabbatical. Haven't seen it in at least four years. Been meaning to watch it again.
