I've been watching it off an on since it started this morning.
I don't get as excited about Le Mans as I do about the Rolex 24 at Daytona. Although the I like the history of Circuit de la Sarthe, the speeds are faster at Daytona. Plus I think Le Mans, and ALMS for that matter, are flawed in that there's too many car classes. Sometimes certain classes only have a couple cars in them too.
I like the Rolex series for better balance. Since the bio-diseal cars came to endurance racing, they've had a huge advantage. Even the addtional weight put on the cars in the 24 Hours of Le Mans this year doesn't make much difference.
