Overall, the drama is nearly excellent - if not for the ending, I'd have given it a 10.
There was a lot of misdirection - and not in a good way. I felt cheated afterward, like I'd been led on a merry chase, but it turned out to be a drag hunt. Foreshadowing that doesn't pan out is not satisfying viewing. There is only one great plot twist - and it's worth waiting for. I didn't see that coming.

The whole time, you're waiting for the satisfaction of the truth being revealed, but it's a hoax from beginning to end. You don't even get to find out who the father was.

However - I fell in love with the cast, and wouldn't give up the time I got to spend with them, in their story, at all. I do NOT regret watching, and might watch it again someday just for very relatable characters in the story. I wish I'd known at the beginning that the ending would be disappointing - zero ultimate satisfaction for the viewer - then I could have enjoyed for what it was - and the story was very nearly great. Definitely WATCH IT - but take it in stride. I don't think anyone will regret watching it.
