Season 4 was a big swing with the whole concept of parallel storylines that converged together in the end, with each episode being the same events but from a different character's perspective. It certainly didn't have as many classic moments as the original seasons had, but it gave us a few new gems, like the To Catch a Predator scene. Not quite on par with the first three seasons, but it was enjoyable for its own reasons.

Season 5 was mostly forgettable, with more aspects that stuck in my memory as having had annoyed me (like pretty much every Tobias scene and his side plot with his little family) than instances that stuck out to me as funny (like Maeby's side plot at the senior center). Add to that how little Lindsay was featured in this season at all and the fact that Jessica Walter (Lucille) had died shortly after this season, I am pretty confident that any attempt to continue the series would be a failure.
