It tries, I guess.
I can't say I enjoyed 'Dolly Parton's Christmas on the Square' at any moment, though it does have (minor) peaks and (major) troughs. Some parts are OK, a couple of the songs fit and there's one nice scene between Christine Baranski (Regina) and Selah Kimbro Jones (Violet). Parton, meanwhile, is fine in her role.
However, the rest is a slog to watch. Far too much emphasis is put on the musical numbers. Yes, it obviously needs them but you must also have more meat on the bones if you're going to make a film out of it. The plot is tedious to watch unfold, as you know what's coming and it doesn't do anything to throw you off the scent.
If you just want a music-filled film then head this way, if not it's probably best to avoid.
