I thought KISS were pretty epic last night. I was impressed with the set list and surprised that they played the full 2:15 and still left out a few gems (e.g. Dr. Love, God of Thunder, I Want You).
Highlights for me were: Let Me Go Rock'n'Roll, Parasite and Cold Gin.
I could see not being impressed with the show if you're not familiar with the material or just not into the whole KISS schtick but I loved it.
Great crowd too with many people dressed up as KISS members, from simple face paint to full on costumes. It was pretty awesome.
Here are some photos I found on flickr.
