I have to say, i adore the brucas friendship!! They are really sweet together, and luke provides great support for brooke. however, i don't think they mesh well as a LOVE couple. i think that while they were together, a lot of it was just about sex and more superficial stuff, while as friends they don't have that stuff in the way, so they can really love eachother for their true selves (in a friend-y way!)
i also felt that, although always sweet to lucas, brooke was always trying a bit hard to be romantic and lovey-dovey. i think this really affected the way i felt about them, because with leyton, there is a deeper connection- look how long they lasted without sex, while dating! i just couldn't see brucas doing this. but as i said, once the sex is out of the way, they can finally have a deeper connection as friends, not lovers.
ok, i have more, but i'm going to bed now. thanks for readin :)
