This 2018 tour has definitely been better than the last few. I love watching Sagan ride, he's a brilliant sprinter, but unlike the other sprinters, a few hills on the course isn't going to kill him. The guts he displayed getting through the last mountain stage while being badly banged up from the crash was amazing. I'm a fan of Tom D so it was nice to see a great showing by him. Roglic was a pleasant surprise as well, I'll be rooting for him in the future as well.
The bad/boring were the doping scumbags from team sky. They had a scare when Froome crashed in stage 1, but other than that, them getting the top GC rider was never in doubt. The other contenders just don't have the horsepower to get away from the sky train. Sure, Quintana did, but he wasn't a threat at that point. I hope that team burns down like US Postal.
