I'd have to say JAG but my roommates changed my schedule & I watch Gilmore Girls instead (& watch hours of JAG whenever I go home where they are taped) fortunately I like my roommates tv likings (she's the one that got me hooked on Alias) so I'm definitely no expert on this show yet but I'm learning
I liked it at first but slowly lost interest (but Noelle/Felicity was definitely the couple I always rooted for) had they ever gotten together I probably would've started watching again
