well, the first week has some interesting moments (cobbles, Mur de Huy, Mur de Bretagne, the rout of the TTT would also be great but it has one gigantic problem...it is a TTT) and I also like some mountain stages (Pra Loup stage, Tourmalet stage, Glandon stage) but all these interesting mountain stages are not difficult enough. So the GC contenders will concentrate on the really hard mountain top finishes which will probably be very boring because, the stages are not long ennough or there are no other climbs near the final climb.
We can just hope that the fight for the gc wont be as boring as in the last three years (but I fear it will be)
