Went here the past two years for the Monster Jam World Finals. On the one hand, the parking is on a dirt lot and a bitch to get out of....but it's free, so I'm fine with that. Most big arenas/stadiums charge, and can charge upwards of $20 just to park...and have similar traffic issues!
Seating was fine, and I enjoy a large police presence. Now that I'm traveling with my own family, small kids and such, I like having university police and Las Vegas Metro around....I used to watch Raider games at the LA Coliseum when I was a kid and saw way too many knuckleheads fighting, gang idiots, drunk idiots, etc. Not worried about it at Sam Boyd. Facilities were fine, although they could have better food to choose from.
4 stars for the security and not charging for parking.
