I thought the performers (drivers, riders) were great. The motorcycle jumps and the fire-breathing dragon got the crowd fired up the most. The two MC's definitely put their all into it, but everything they did was really geared towards the kids who were there, which is fine. The pre-show Crash Zone is really for the kids as well. The lines for each driver are relatively long, and you simply get them to sign a program flyer they give you when you enter the arena. Meaning, if you want to ask about the trucks or bikes, this is not for you.
One quick criticism (if you will) about the show itself, it stopped after each run in each event to ask what score the driver got for their run, and then introduce the next driver. Then after each event, they would interview the winning driver. This constant stop and start kills the energy built up in each run. The reason the crowd got louder during the motorcycle jumps is because they didn't stop after each person jumped to say now someone else is going to jump. (Note: The scores that are handed out start to make everything very scripted. When you can tell that one driver did a great job and they get the same score as the one before who didn't do as well, people ask what's going on.)
Again, really great job by the performers. Kids will have a blast; many adults will too. Cut a 1/3 of the MCs speaking to the crowd out of the show and fix the writing so it doesn't appear to be so scripted, and you'll get a crowd that is way louder and more motivated throughout the entire show.
