Well, I think that the show was much better in S1 and S2 than in the two later seasons. Just think about the Wedding ARGH or the amnesia arc - we didn't have anything like that in the first two seasons. IMHO, the writers should have stuck with Debora Joy Levine's original idea to not let them get together before season 5 or 6. (At the very least, that would have meant more seasons for us to enjoy. Even with a pregnant Teri - maybe we could even have gotten an arc where LnC did get intimate to write the pregnancy into the series?)
