My thoughts on the Stadium...
First off, I'm not going to debate the history/nostalgia because that's an unfair comparison. In fact, I'm sure older fans had the same opinions in a 'Cotton Bowl vs Texas Stadium' debate 40 years ago.
With that being said, maybe it's because of the 'old school vs new school' generation gap or something, but Cowboys Stadium doesn't feel like it's the "home of football" nor "home of the Dallas Cowboys". It feels like I'm inside a Las Vegas casino.
Texas Stadium felt like it better celebrated the Cowboys. Cut the stadium walls and it seemingly would ooze blue and silver. Go to the front entrance and Tom Landry's statue will greet you along with this huge concrete Star. Texas Stadium had huge murals of Staubach and other Greats adorn the outside facades. The Ring of Honor was prominent. On field level, the walls were covered with those white plastic Stars (Mike Furrey knows). No jumbotrons, just bleak dot matrix scoreboards -- However, the spartan and simplistic decoration indoors further showcased its one feature and you couldn't help but focus on it -- and that one feature was the midfield Star.
Cowboys Stadium does everything it can to distract you from focusing on football. There are go-go dancers on crow's nests. There are two bright & annoying LED 'band boards' that circle the perimeter and they overwhelm the Ring of Honor, making it look like an ugly daughter hidden away in the family portrait. There are cover bands playing outside, party decks with Ford F-150s displayed.
Of course, then there's the JerryTron. Now, I love big TVs, but honestly, the JerryTron is overwhelming and a disruption. Imagine trying to sleep with a strobelight going off in your face.
Moreover, it feels like it could be the home of any NFL team, not just the Dallas Cowboys. Tom Landry's statue is placed in a random spot, almost like a porta-potty. The artpieces are great for a museum, but how about pictures of Meredith, Staubach, Lilly, Dorsett, or the Triplets instead? Gone are the Stars on the walls field level (only a couple remain in the end zone) and they're replaced by the suites.
Lastly, Cowboys Stadium is humongous. As a result, it loses some intimacy and coziness; the fans across the field seem like they're worlds away.
All in all, the stadium is an architectural marvel, but it doesn't feel like the home of a football team and certainly could improve its Cowboys-ness.
