What the heck is going on?!

OK, the reviewers praise it when the season starts. So I watch. I get hooked. Then ABC cancels it.
Then this August it comes back--yea! ABC show us 2 new episodes for the past two weeks, so I get back into it.
Then I tune in last night and it's NASCAR???? ABC what are you doing?? When are we ever going to see how it ends? Stop messing with us!
