To be honest, In my opinion thats the only true way to enjoy it as a fan of the event. If you are willing to take things in stride and don't compare the event to some previous expectations in your mind, you will enjoy the event far more, and overall it will have been a much better event as that year's season comes to a close.
Some people will be disappointed regardless, but that is the way of life. I mean, sure, nothings ever PERFECT 100% of the time, and sometimes I think people need to realize that. Not to say that Criticism is necessarily a bad thing tho, I mean when criticism is heard, then the changes it can lead to can lead to a much more remarkable event in years to come. There is a difference between criticism and an angry tirade over everything that went wrong with your trip, you may have just had a bad night, it happens sometimes, but hopefully you can enjoy the event for what it is, and look forward to a better event in the future...an optimistic viewpoint going in certainly helps you enjoy that years event, and certainly the event as a whole.
And With That...Happy Speculation Everyone
