I recently went to the NFL game at Wembley, that is how to make a show. I found the entertainment between the plays more enjoyable to watch than the actual game itself. In fact it starts before you even get in the ground.
Stages outside with music, bands, give aways , interviews with fans, Inflatables etc.
Inside Wembley was immense. Atmosphere at times was electric. American football can be dull to watch but they really do know how to get the crowd going.
Was it too 'artificial' ? To the older generation , probably. I found it refreshing to be honest to be treated as a customer first, supporter second.
