This is generally not my kind of movie. It's a "weeper," and I avoid weepers. Nevertheless, I tuned to it out of sheer curiosity -- the show (and the book) was technically based in my home town of Three Rivers, Mich.
I couldn't stop watching. I enjoyed the story and I enjoyed the performances.
The nit-picks I have are minor, in the broad sense. Living in Three Rivers, I could easily tell the movie was filmed in California, and I understand that it needed to be filmed there for economic reasons. The grass is wrong and the trees are wrong. I had to snicker at the mountains clearly seen from the "train station" in the movie. We have rolling hills, not mountains (and we do have rivers... not one scene of a river, that I can remember.) The houses around here are generally either Victorian style (on Main Street) or, further out as the town expanded, 60's era Ranch-style. The streets are straight, not curving as on "Sycamore." The church was... I dunno... looked like some kind of smooth material; most churches around here are brick or have siding.
Only a native of Michigan would notice these minor things. Still, the themes are universal. Couldn't they have set the story in California, where it was filmed?
