Do you prefer.., to read a series or single-story book? Options

So I was wondering when the next Shopaholic book will come out and I said to myself I hate waiting for the next book in a series to come out. Which got me thinking. . . do you prefer to read a series (like HP or The Wheel of Time), a Trilogy (Like LOTR), or a Single shot book (Like The Redeption of Althalus)?

Personally, I think I prefer a trilogy best. Long enough to get a lot done, and if done correctly excellent character development and story telling. But some series' I like too, like the Riftwar Saga, Incarnations of Immotality, and HP. But some series turned me off, specifically the Wheel of Time, and The Bellgariad. The Redeption of Althalus was a nice long book, and was/is a single shot deal. Perhaps that one could be a trilogy. . .

Anyways, what do you prefer to read?

One book.
Sometimes, the author gets lazy with the sequels. I hate bad sequels.
Kills the character and stuff.
Good sequels are awesome though. ( eg LOTR and Harry Potter. )

True, i like both styles as Jose said authors get lazy and make crappy sequels, BUT some are really good.
