I liked Avengers and some of my best times were at Disneyland
Also, I visited Thor's forest across the river from Heidelberg and recommend a summer in Germany (don't use tour buses). Go tour on foot and take trains. Stay on the opposite side of Rhine from tourist traps to really see the country and people. Learn some of language before going.
Heidelberg is super and you can see the castle where King James was born and the church of the Holy Spirit, and places where the Reformation was born, God's counter movement to the Renaissance happening in Italy
