They did indeed destory ALL characters and all ships, just about.

Personally I found Chloe's completely inconsistent characterisation more annoying that Oliver's out-of-character plot (because I don't like them scripting him as Lex's killer either)--Chloe has advocated that Clark kill Lex!!! Do the writers even watch the show?!

Good on MR for turning this shit down. It was TOTALLY disrespectful to his character and I can't believe they wrote it. The Lex parts were almost the worst for me and that's saying something considering they killed Clana and Clois in the same episode....
