Random question for you guys. I was just thinking about this earlier and I was wondering how you all feel about this topic.
What would be, in your estimate, the show(s) with the best opening episode?
I'm not talking about the opening animation, and the entire series could collapse later and suck, but that first episode just drew you in and didn't let you go. I'll throw out my personal nominees, though I only plan to talk about a couple shows.
Ouran High School Host Club
This show sets up the entire premise and primary cast in it's first episode. And it did so brilliantly with great pacing, comedic timing, and showing just enough characterization for each of the seven main leads to get a good feel of who everyone is and what they're about at a glance, with a nice little "gotcha" at the end to surprise you and make you want the next episode right away.
Cowboy Bebop
A small, quiet scene is followed by a bombastic opening, leading into a laid back beginning where we're introduced to Spike (or Bebop the Cowboy if you prefer) and his partner Jett. We learn they're bounty hunters, and get a small glimpse into how their lives are about excitement (the fight scene in the square) but also can have some tragic results (the escape attempt for the bounty). This episode completely encapsulates the entire tone of the show to follow, some action, some laid-back scenes, and some bittersweet and/or tragic moments.
