I thought the bridges were very cool. Really well designed, classy even. I would not be surprised if other arenas start to adopt that design. I'd like to get those seats for a game or 2, but not for a full season.
I agree that the flow has improved and you really get a sense now that it is "done", whereas after the first phase, expectations were very high and it was somewhat disappointing on opening night. I guess that is just the downside of not being able to complete the entire reno in one shot. I imagine if it had gone from the old Garden to what we have now over the course on one summer if would have been an amazing opening.
Yes, the Garden was very quiet last night, but I think a lot of that can be attributed to the late opening after a dreadful road trip. So, it's not the first or second game of the season, when the minds of the fans are filled with "anything is possible". We pretty much already know what kind of team we have. Also, it's seems to have different acoustics, as well as a less enthusiastic crowd. Opening night after the LAST lockout was crazy, and we hadn't made the playoffs in 7 years!
