Perhaps not a "love child," per se, in that the boy seemed less than 7 years old and Chloe and GA could be married. But otherwise, yeah, definitely the vibe!
I felt appropriate rewarded by the show, watching nearly every one, though I do wish they'd ended it much this way a couple of seasons ago. Still, glad I've watched, through the (sometimes very) bad and (rarely very) good.
Right. I only say love child because in normal DC continuity Green Arrow is with Black Canary. But Smallville has already established that it goes its own way (the murder of Jimmy Olsen) even if they sometimes hedge their bets (his twin showing up at the end as the new "Jimmy")
I also agree that over the show's run they had some really good eps and some awful ones. In my opinion, the show really took off once Lex was "dead" and Millar and Gough left the show. They seemed stuck in a rut until they really started mining the wider DC universe. Then it got enjoyable again.
Over the years, my least favorite bits about the show were:
Too many freak of the week eps - That got old in season 1
Lana - she should have left and stayed gone back in the middle of the show's run
Too much reliance on Kryptonite as the MacGuffin that depowers Clark. I mean seriously, the stuff showed up everywhere.
Too much Clark angst and self-doubt and too little trust between core characters who are supposed to be friends. Like Clark and Chloe, or Clark and Oliver.
My favorite Smallville bits were:
Christopher Reeve and any ep with him in it, especially the first one he appears where he explains about Krypton to Clark. Powerful stuff.
The ep where mortal Clark dies, comes back and then superleaps to stop the nuclear missile. Good stuff.
The season 9 ep where Clark goes to the future and sees his destiny and then finally tells Lois his identity (though she already knew)
The season 3, 8, 9, and 10 finales were all well done. Season 3 had that awesome montage of classical music while Lionel shaves his head before going to prison, Chloe's house blows up, and Clark gets taken by Jor-El. Season 8 had the death of Jimmy. Totally did not see that coming. And Season 9 had the cool finale with Zod. Season 10, well, he became Superman.
The death of Clark's dad was good and the choice that cost him his dad.
Lex finally snapping and killing Lionel was dramatic too.
Anything written by Geoff Johns or that really touched on the DCU stuff like the season 6 Justice League ep, and the Season 9 JSA eps.
I also liked all the cameos by Superman alumni such as Christopher Reeve, Margot Kidder, Dean Cain, Teri Hatcher, Helen Slater, Terence Stamp, and of course Annette O'Toole.
