TV That Sucks Me In

Why is it that no matter how many times I've seen an episode of a show, I'll always get sucked into it? The other day I caught an episode of "The OC" on the SOAP net. It was from the first season. I've seen the episode probably half a dozen times an I even own the season on DVD. I still sat there and watched it like I'd never seen it before. I got sucked in because it was an episode with Anna in it. I loved Anna. She was so smart and had great fashion sense. Plus, it was the one where Oliver goes all crazy and holds Marissa hostage. Awww.... I miss "The OC."
