I haven't seen the full series run ever, and the last episode I watched was a few years back before the DVD came out and bittorrenting was kinda new and my computer was so crummy it could barely play a 60-minute AVI file. Before then, I only caught it in 1999 during its very sporadic network run when it wasn't busy being pre-empted or getting cancelled.
I've picked up a lot more notes in the writing in the 10 years since I saw more than one episode. Back then, Mid-20s Me picked up on a nostalgia factor and the high school factor and the crush on a girl factor and the fitting-in factor. Now, Mid-30s Me is picking up on disappointment, adult regret, the realization that dreams will be crushed, and the lasting unease and uncertainty that comes with not knowing where the hell you're going anyway. That the show refuses to end any episode except the pilot with a typical "happy" ending helps underscore a lot of that.
Still, it's a wonderful show. It manages to make you laugh like hell one moment, then rip your heart out and stomp all over it the next, and after that, make you laugh like hell again, only this time with a stomped heart.
I got a few more episodes to go. Guess I know what I'll be doing with my week.
