Indeed it is... and that was my first encounter with Bradbury, at the age of 7....
No, it isn't considered lame at all to like Bradbury's work -- he is simply one of many wonderful writers who have not got enough discussions going about them to warrant a sub-forum of their own... yet. On the other hand, if you do a search for Ray Bradbury, I think you'll find bushels of posts about him, as I know there are quite a few fans of his work here.
While I by no means have all of his books (though I hope to eventually do so), I have a fairly good selection (albeit I need to catch up with one or two of the more recent ones, such as Forever Summer -- a sequel, as I understand it, to Dandelion Wine), and I revisit Bradbury from time to time -- sometimes for an extensive period. One of my favorite books is his first: Dark Carnival. It has the earmarks of a young writer, true, but he did something special with that book that I've not encountered with anyone else writing such tales, and therefore it stays with me over the years.
Let's hope you can get a few good discussions going about the man and his work... I'd like to see a sub-forum devoted to someone who helped to bring sff into general (critical, at least) cognizance as a form of genuine literature....
