There's a lot in Cross Creek that's excellent. Several fascinating performances create well-honed characterizations of complex, sometimes-likable characters.
The visuals are beautiful, mostly shot on location in Cross Creek. It certainly evokes this part of Florida. (I grew up about 25 miles from the setting.) Some negatives lower my rating. But despite these, I still highly recommend the film.
Though many like the score, I found it mostly sappy, the only exceptions being the music created by the characters.
Summer never seems to come. Once we see MKR wipe her brow. We get no sense of the oppression of the summer heat and humidity.
But likewise, winter never seems to come. For goodness sake, when you're lighting fires to protect orange trees, that's because it's FREEZING! Those orange trees won't be hurt above about 25F. And freezing weather in Florida is normally accompanied by wind. This may not seem like much to those who live farther north, but it requires more serious clothing than most of the characters don. Yet none seem to notice that it's cold. And MKR's house wouldn't have been so well heated that she could sleep in that weather with only light clothes and covers.
It never gets muddy. The movie shows some torrential downpours, yet when the characters get back out on the roads and paths, it's all dry and neat. That doesn't happen in the swamp.
And it never seems to get buggy. We hear a couple of mentions of mosquitoes but mostly they don't seem like a big problem. People just sit and walk around with no sign that they notice.
