I tend to think any kind of illuminated figure, inflatable or otherwise, looks tacky--and that includes illuminated plastic Nativity sets. 
Oh.....well.....confession time! lmao
My mom puts one of those light up nativity scenes on the front porch each year with a white sign with red letters that read "Happy Birthday Jesus"

I understand she likes it, I just think it looks juvenile.
I keep telling her that one morning, she's going to wake up to see I've put party hats on Mary and Joseph, and put bday balloons on the manger.
