Just about enjoyable.
'Christmas at the Plaza' gets slightly uninteresting in parts, but I largely had a solid enough time with it. I enjoyed the hotel setting, as well as the heavy Xmas vibes. Elizabeth Henstridge is good in the lead role, her (Jessica) and Ryan Paevey (Nick) have suitable chemistry. I also liked Bruce Davison as Reginald.
The story is a pleasant one, which involves a decent amount of heart. It's, albeit narrowly, worth a watch.
