Oh my goodness! I nearly posted almost this exact same topic. I have read Blue Smoke and Carolina Moon, but not the first 2. That said, I watched Montana Sky and most of Angels Fall, as well as Blue Smoke. I thought Montana Sky was ok. It started feeling very predictable after a little while-as in the lines, that sort of thing. Angels Fall started out pretty good, but then I had to leave, so I missed the end.
I did not like the actress playing Reena in Blue Smoke as Reena. I did like how they incorporated the past fire scenes by using flashbacks. Overall, it was just ok. The special effects were horrid. They looked worse than 1970s movies. Just way too outdated.
I'm looking forward to Carolina Moon. I really like the lead actress. I didn't love that book so much, but I'm holding out hope for the movie version.
