I whet my appetite on the _Prolegomena_ and got food poisoning. It was a quagmire of restatements that left me no appetite for the full Critique. Do you think I'm missing anything?
There are gems hidden in the slag that make the attempt worthwhile, IMO. Keep in mind that you don't have to buy into the whole thing - I certainly don't - in order to see that some points are useful on their own. As an example, I'm not a Kantian, as I said, but the basic utility of the categorical imperative has held my interest at times ;)
