What are your thoughts on A Real Pain?

I mainly watched it because I love Kieran Culkin in Succession, and I thought it was really solid. Nothing outstanding, but it feels like the phrase ‘nice little film’ feels like it was invented for this movie. Here is my review for it: https://m.youtube.com/watch?v=lh24WtsUAyA&t=0s. The performances, dialogue and cinematography were pretty great. What are your thoughts on it?
