Words really can't express my feelings towards this show. Sadly I've watched too much television, and when you do, you tend to really embrace what's actually good out there. That '70s Show is the best I've ever seen, and I've enjoyed shows like Seinfeld, Simpsons, Friends, Frasier and the like. For me, this show tops them all.
Maybe it has to do with revisiting your own past as you sort of revisit the past of the makers of this show too. Following the hilarious stunts of the Wisconsin kids as they stumble through their teens cracks me up every time I watch an episode. Watching Donna and Eric's growing relationship, the stupidity of Kelso, Hyde flirting with his left-wing philosophies and small time would-be criminality ...and so on and so on... really makes the stress go away.
The show is a wonderful mix of good humour, touching on important themes with not too much seriousness and striking the chords of the human soul. *sniff* Gotta spin the disk too stop the tears of joy flowing... ;)
