I would say harry potter, I have a soft spot for Harry. I watched him grow from the adorable kid to Harry a teenager.
The Harry potter series is a better one to watch, but the books are really good when compared to movies.
Definitely the Harry Potter series out of the two for me, but like said above the Harry Potter books are a lot better than the films. I'd probably rather read the Harry Potter book series than watch Twilight Saga, it's really not interesting enough for my liking. Harry Potter is more... Sophisticated.
Twilight Anyday. Team Edward here! Wasn't originally into series but if i had to pick one, it would be Twilight. it's the only one of the two i would thave the patience to watch.
I'll go with Harry... vampires aren't supposed to be pleasant lovers... they are savage beasts to which tear your neck apart and feast on your blood.... and harry... well... forget about him and show me more of that emma what's-her-face and I'm happy
I have seen two of the harry potter films and one of the twilight films and as films there both rubbish but fans of the books eat it up like they havn't seen better films. I can't judge on the books because I havn't ready any of them but I have heard the books are far better.
