I've lived in New England for many years and I've never been to a Patriots game or actually watched a live event at Gillette Stadium. I have, however, been to many NFL games in different parts of the country and quite a few in Orchard Park.
A friend and I went to the Pats/Bills on Sunday and it was a horrible user experience, the game not withstanding.
1. Constant, excessively loud hard rock music blasting from the speakers throughout the game. Now, I'm a big rock music fan and loud is good, but this was way over the top. It was clear that whomever was in charge of the music was playing their own personal favorites as AC/DC and Motley Crue ruled the day. I can't imagine someone with a family actually tolerating this >90db hammering during the entire game, barely cutting off when the ball was in play.
2. Constant flow of people in the aisles as well in and out of their seats. I must have stood up more than 50 times to let fans out or back in to the row. I have no clue what they were going to do, but I've never seen this much activity not related to the event, anywhere. Not at a sports event, concert or any live performance. It was baffling.
3. People standing up when there was very little going on down on the field, so of course we have to stand to see the field and then the people behind us... Some folks actually stood up for most of the game talking to their friends, not watching the field at all.
4. Maybe I'm spoiled, being from Buffalo, but $125 tickets, $50 parking, $8 for a hot chocolate are a ripoff given the user experience inside the stadium.
