second date help!

so I went on a first date with this guy i’m 20 he’s 23, we went to dinner and walked around town for hours talking about each other and getting to know one another, for the second date he wants to order pizza and watch some of the harry potter movies I haven’t seen at his place, is that a good idea for a second date?! im so new to the serious dating world rather than dealing with boys at college and don’t wanna be forward by going to his house on the second date ya know?? idk maybe over thinking it
