I'm sorry but there should be at least two decades between an era and nostalgia for it.
In the 70s there was 50s nostalgia (Grease, Happy Days, Sha Na Na)
In the 80s there was 60s nostalgia (the Big Chill, etc.)
In the 90s it was the 70s (Travolta's comeback, etc.)
Etc.
We aren't due for I Love the 90s for another six years tops dammit!
