It's nice inside and the sound quality is great BUT I've been to 2 shows here where I was GA, and if you are not in front you will not see a thing especially if there's tall people in front of you. I guess I should stop buying GA. Also, they charge $5 for a bottle of water and do not let you bring any inside. Not cool.
Edit- They recently updated their security procedures which is great! Thank you Comerica.
