Babylon 5 is a weird show for me. When it was first running, I religiously watched it. If I couldn't watch it live, I got upset and went around my circle of friends to see who'd recorded it so I could watch it as quickly as possible. Up to Season 4 I was gripped. (Season 5 was "meh" because of production shenanigans.)

Years later I watched them on DVD and ... the magic was gone. Watching one episode after another, without separating them by a week, just took the shine off of it. I didn't even finish watching the episodes on DVD; I think I made it to mid season 3 (and the amount I watched slid down and down up to that) before not bothering to continue. I eventually gave them all to a friend of mine and never watched the show again.

I can't think of a single show I've ever watched that had that weird impact on me: first loved, second bored. Usually shows I loved I keep loving, shows I was bored by remained boring, and very occasionally a show I thought was boring the first time got more interesting on second viewing. But B5? It's the only one that goes this way.
