The main plot is sometimes claimed to be a bit meagre, but I disagree, it is quite enjoyable. Besides that, some shorter and longer intermissions are added with theological discussions on heresy, description of visions and buildings, but these are, although a bit boring sometimes, vital to the story as a whole. Many of these things are explained in the enjoyable epilogues. A 'classic' worth reading, not on my top list, but very close! Makes me want to read a lot more of Eco's works!
