Haha :) You've missed out my friend, I highly recommend to at least watch the Harry Potter films you haven't seen (especially if it's the later ones). From the 3rd movie, the quality and maturity of the films are wonderful.
The story of Fantastic Beasts takes place about 70 years before Harry Potter was born so obviously a lot of the characters from the time of Harry Potter won't be in Fantastic Beasts, but it IS confirmed that none other than Albus Dumbeldore will appear in the 2nd Fantastic Beasts and onwards as well as Gellert Grindelwald who is considered the most dangerous dark wizard of all time after Lord Voldemort. Could for sure be others too.
Had a discussion with two of my friends about this, and want to know you guys' opinions as I respect them and am curious what you think. This is completely off topic from football, but in these days with the boring international break etc. I guess it's fine. Me and my friends landed on this list:
1: Harry Potter
2: Star Wars
3: James Bond
4: Middle Earth
5: Batman
6: Spider-Man
7: X-Men
8: Star Trek
9: Transformers
10: Pirates of the Caribbean
State what you think as well. Take into account everything: amount of fans, commitment of fans, box office, budget, legacy, amount of movies, etc. Especially curious about 1st place.
PS: Don't count Marvel as one franchise as this would just make the list uninteresting; rather separately as one Avengers, one Iron Man, one Captain America, one Thor, etc. Same for Pixar.
