I read the Robin Hood series. The first one does start slowly, but I enjoyed the rest of the books as well. I can't speak to the current series though.

I know what you mean about not being sure if you changed or if the author changed. I liked some of Brandon Sanderson's books, but haven't been as impressed with his recent works. I ended up regretting buying the most recent one I got and doubt I'll get the next installment when it comes out. We'll see though.
