Should the Twilight Saga have been made into a mini-series (like The OC) rather than into movies?

Do you think that the Twilight Saga would have been better and more in-depth if it had been made into a mini-series (something like The OC) rather than a movie of each of the books? I sometimes feels that if a series had been made rather than movies, we would have seen more of our favourite parts of the book come to life and it woudl have lasted longer!! What do you think?
