There was definitely no need to beat the crowd and you could walk right in without having to wait in line, so that's a plus. The doors were schedule to open @ 6:00 pm and the event set to start at 7:00 pm. They did indeed open at 6, but absolutely nothing happened until 7:45 when the main card line up was announced. After the undercards finally began a little after 8:00 pm.
There is no preshow entertaiment, no meet and greet with the fighters, and only over priced concessions available to consume. So, make sure to have a friend along to pass the time with if you arrive early.
Because only a small section of the arena was sold it meant the 2/3 of the arena was empty and the sound engineers did not take this into account when setting up the microphones. Due to the echoing off of all that open concrete the ring announcer and post fight interviews were utterly meaningless. You simply could not decipher what was being said.
The fights were entertaining for the most part--two of the eight really stood out as excellent fights. One, the fourth and last fight of the undercard was easily the fight of the night and the 1/3 of the arena was electric with excitement. The second fight, the headliner, was also very enjoyable. Unfortunately the three fights between the fight of the night and the headliner left a lot to be desired.
If there was some sort of entertainment available for the 2+ hours prior to the show starting, or if it had started as advertised, I would have rated it higher, perhaps three stars. Couple that with some better sound boarding so we could understand what was being said and who was fighting and I would have definitely rated this 4 stars. But, it is what it was.
