Smallville

I've been a great fan of Smallville since the first season. For those who have not heard of the series, Smallville is the story of young Clark Kent before he becomes Superman.

Why do I like the series so much? Maybe because of Tom Welling who potrays the young Clark Kent and Kristin Kreuk who plays his love interest during his teenage years, Lana Lang. For me, they are the perfect couple on screen but then, sigh......throughout Season 1 to 6, their love life is like i-love-you-you-love-me-but-we-can't-be-together for the million reasons in the world.

Clark left Lana because he is afraid he will get her into trouble, Lana left Clark because she feels that Clark does not trust her (by not telling her his superpowers). There are many close encounters where both gave each other a chance, and the secret is revealed but in the end, Lana will end up having amnesia.
Now, way into Season 6 (spoiler ahead), Lana got married to Lex Luthor, Clark's nemesis. She did this to protect Clark as she was blackmailed by Lionel Luthor (Lex's father) because Lionel knew Clark's only weakness, kryptonite.
