You could almost watch this without the first two, but I started watching this with no clue it was a trilogy and immediately realized I was missing backstory. It is partially filled in but it's a little rough catching up. I found the other two.
This is more of a romance but there is still a lot about finding yourself. I think this is where watching the whole thing helps. There are some elements that follow the typical romance from Hallmark. It has a current fiancé vs the old hometown sweetheart. That part is the usual, although the loser has maybe fewer flaws than most of the rivals I've seen in other movies.
Overall I probably didn't appreciate this as much as the other two. I can't say I "enjoyed" the first but I did appreciate it. The second was enjoyable. This wasn't bad, just not as good.
There's a point where Katherine wants to say grace and Justin is shocked. This far into their relationship is a little late for him to realize how strong her faith is. She certainly has wanted to say grace before.
There is a strong Christian vibe to this movie, and not just Amish. But there is little preaching.
