I'll give it a try but I missed season 4 because of Lost. Most of my friend gave up on it about half-way through Season 2 and only stayed for Lex and Lionel. I know the entire romance focus on Clark and Lana has enabled them to keep the teenage girl audience and thus kept the show on the air as long it has, but it just sucked a lot of the fun out of the show for me. Even your most casual Superman fan knows that anything to do with Lana is doomed from the start. She is not The One. I did like Lois' apperances, both because she as done as a likeable character and because, well, she is The One. I'm thinking this season almost has to be the end, or perhaps next one.
