I thought Romano had some nuance and layers in Season 6, around when Lucy died. I think they often lazily reverted to type with many characters later, him included. The helicopter shenanigans and other stunts before and after always smacked of them constantly trying to top the big Lucy scenes - shock and more shock for sweeps. I was long gone by then. This and the unrelenting misery of certain storylines for certain folks (like Mark) is a big part of what drove me away; that and the blatant attempts to just clone Carol and Doug repeatedly with Abby, Luka, Sam, etc.
