Practically indistinguishable from the original, which I guess is a plus for a made-for-TV sequel.
'Christmas in Evergreen: Letters to Santa', like the 2017 film, is lacking something. There's again nothing particularly negative about it, it's just missing a thing to turn things up a notch to create a fun festive film. The plot change-up is solid, it doesn't improve upon the first's but it's just as OK.
Jill Wagner is a step up from Ashley Williams, though the latter was good too. Mark Deklin, however, is a step down from Teddy Sears. I didn't buy into the relationship of Lisa (Wagner) and Kevin (Deklin), I didn't sense enough chemistry - same with the secondary love story, featuring Holly Robinson Peete (Michelle). I do like how they did the continuity, at least on the surface, despite the cast changes.
Overall though, like its predessceor, it's too bland.
