Nostalgia can be a real money maker -- who knows how many of us 40-50 year olds with money to spend are waiting for that dream theme that takes us back. . .
Batman 66, Superman 78, What would come next? The A-Team 83? Back to the Future 85? Mad Max 80? (technically '79, but I think it was '80 in the US).
I'd be tempted by any of those and more. . .
