Some people, alas, just do not like Bach. If you have not done so already, I'd suggest listening to some of his vocal and non-keyboard instrumental music, St. Matthew Passion, B minor Mass, Brandenburg Concertos, Violin Sonatas. If none of that says anything to you, then the keyboard music probably won't either.
For learning the fugue, try writing it out in parts as though it were for two violins and a cello; that way the structure will be really obvious, and understanding the structure in more detail may make it interesting to you (this is assuming you're not a grad student who's taken courses in counterpoint and fugue writing and can just look at the keyboard score and see everything immediately).
