I went to the American Cup and enjoyed it in person - I went home and watched the DVRed broadcast, and yeah, it was a lot more lackluster than it was in person. Sam Mikulak's air flares on floor were my favorite skill all day, and yeah, he and Fabian were cute together between events. I know it's not a popular opinion, but I really like Brenna's bar routine, although it could stand to be cleaned up. The women's competition was never close but the men's was a nailbiter until Nonomura fell on the last rotation.
The biggest disappointment to me was that the crowd - while huge in number - didn't care much about the actual gymnastics being performed. The biggest cheers all day, by FAR, were for the T-shirt cannons between rotations. I got pretty irritated during the last rotation because the huge contingent of preteen girls was getting bored and were dancing along to floor music in the aisles, blocking people's view of the floor. Sort of sad that the actual competition seemed like an afterthought to most of the audience.
