I am not so sure that what makes the TDF boring has anything to do with the route alone. I agree with those who said part of the problem is the size of the organization and what they represent. Compared to the Giro , the tour remains a giant, the racing is faster, the stages are longer, the competition stacked with the best riders and yet the commercial pull seems to skew everything to collectively calculated mode that spoil the excitement.
It's more that the Tour is so important that nobody wants to risk being out of the mix. At the Giro you'll have a mix of Italian teams who only get that as their one chance to shine in the year, and they want to be seen. They also invite teams of nothing but pure climbers, who often bring a lot of excitement to the race. You also have people who are only using it to warm up for the Tour, so race the first half hard, to test themselves. At the Vuelta, you have people who are dropping out for worlds prep, so you see strong riders losing time and getting into escapes if it helps their preparation (see Cunego last year or Ballan in '08), and you have some quite small ProConti teams showing up who want to impress.
The Tour is a victim of its own success; it's becoming increasingly difficult for the 'little team' to get an invite, and when they do give their national teams invites, the teams are suited to racing all round France, including lots and lots of flat races in the north, which puts them at a disadvantage regarding competing overall compared to the teams only racing the Italian and Spanish calendars. And because nobody is using it to prepare for anything else, everybody has the intention of going for 21 days, which means they won't take major risks in the first two weeks unless they have to; this also means that the péloton will seldom take the risk of letting the break get 15 minutes up the road and will control it much more rigidly, which removes an aspect of unpredictability from many stages. Last but not least, you have the desire not so much to win, but to NOT LOSE. People like Wiggins know in their heart of hearts that they won't win the Tour de France this year, but they are still determined to get that high placing. As a result they'll only race aggressively once their high placing is assured; anything less than a high placing will be regarded as a failure, so they have to ride to protect that rather than aim higher with a shoot for the stars approach. And the successful results of Bruyneel has made that conservative high placement something to aspire to.
