Didn't grab me at all. Doesn't look like it's going to be my cup of tea.
Also, doesn't appear to have any dynamic day/night cycles, maybe a couple of specific night courses. And no weather. At. All. No fireworks either. What happened to the Horizon series being the "fun" games? This looks extremely bland.
No offense to anyone who does like it though, the thread is overwhelmingly positive. But it looks like it's skewing more toward the mainline Forza series than being a sim-lite like the first two games in the series.
EDIT: I stand corrected:
