I didn't get there this year, but it's been great when I have gone in the past.
The large bridges are phenomenal, and so are all the buildings representing many landmarks in NYC.
My only slight negative bias is that I would suggest the night-time viewing they used to promote (not sure if it's every year?) may not really be the best. I felt that many of the scenes within the building benefited more from having the natural daylight help out to see all the details. The lit up scenes at night were OK, but it was much harder to see the details.
(so in case I wasn't clear, I highly recommend seeing this, but see it during the day! 
)
