the 70's weren't all that!
Hi I saw this movie because I graduated from high school in 1976 as well. While this film did a good job of recreating the time, I didn't feel living in that time period was anything special. The real earth shattering decade was the 60's, the 70's felt very mellow in comparison. In fact, we had a huge nostalgia for the 50's with movies like Grease and tv shows like Happy Days and Laverne & Shirley. I think this was because the turbulent 60's were hard to take in and we needed to slow down.
While the FM rock n roll was great, the top 40 radio was more dominated by the likes of schmaltzy ballards; You Light Up MY Life by Debbie Boone was the biggest hit of the decade. The late 70's would start being dominated by disco music, long waits at the gas stations and loosing of America prestige abroad.
