DP really uses its R rating (Iโm not sure, I guess you have a different rating system?) In DP1 thereโs a sex scene, but it does keep things partially out of view, gory, bathroom humor, and lots of pop culture references. Though youโve watched Game of Thrones so the gore and stuff would probably be alright for you. DP2 is mostly just gory in places, Iโd say itโs a bit more tame than the first, but otherwise itโs more of the same. (Which I thought was great, I really liked both movies and liked DP2 even more) Itโs been a while since Iโve seen DP1 so I donโt remember a lot of it, but DP2 was hilarious, I was laughing and chuckling through most of it.
Avengers though is just Infinitely better. (See what I did there? 
) Itโs so well put together, it strings all the films from the past 10 years together so perfectly itโs just amazing. The care and thought put into that film is really something else.
Both movies have their place though, while Avengers is the better movie, they both serve different purposes.
