It is still very young, as a result it's evolving pretty quickly. It's not perfect, but is improving steadily. Track design is getting better. The level of competition is rising. There will be growing pains of course. Rules are coming in line with FIA, which will make cross series competition easier when schedules allow. As mentioned above, red flags diminished as the year progressed. Schedule has ramped up this year as well.
There a lot of good folks working hard on it to make it a success. There will be hiccups along the way. Overall it is in a far better place than it was two years ago.
