Ok, I have a bit of an oldie for you guys. I just started really watching it for the first time since I caught random episodes of it on TV over a decade ago:
Zorro - 9/10 - This is the old Disney show from circa 1957, recently released on DVD via Disney's Limited Edition Walt Disney Treasures line. I got both seasons of the show (39 episodes a season, mind you) and am currently working my way through the first season, and so far I love this show. Unlike most of the Disney TV shows from back in Walt Disney's day, this show doesn't come across as corny and lame and I can easily marathon it. I admit I'm biased with this show: this show has faults, but it does so much well that they don't bother me. This show just has amazing production values for its time, reasonably good writing and acting, a great sense of pacing, and an incredibly catchy theme song. The half hours just fly by, and to add even more value this show is actually pretty heavily serialized with distinct story arcs. Only 30,000 copies of both seasons were put out there and they are a little pricey, but this show comes highly recommended. It's over 50 years old now, but it can easily hold its own.
