A good idea. I agree with almost everything you set up here, and also that Harry Potter is simply the biggest of all in spite of the recent Star Wars rise. I have simply not seen and felt a bigger embrace of something worldwide than when that final HP-movie came out to cinemas. Felt like the whole world was talking and thinking about Harry Potter.
Also agree with top 5, but from there it's very difficult to sayand so many great ones. Some honorable mentions are The Matrix, The Godfather, Terminator, Indiana Jones, Avengers, Toy Story and Shrek.
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.
