James Gunn was clearly appreciative of all the trailer views, thanking fans for "welcoming Baby Groot and Mantis," as well as showing gratitude to the marketing people at Disney and Marvel for putting up with his "eccentricities" during the editing process. Clearly that massive number proves that people, whether they're longtime comic book fans or just Groot fanatics, are still deeply invested in the Guardians two years after their first movie was released. While Marvel has enjoyed years of success with their movies, Guardians of the Galaxy was a surprise hit, using offbeat humor, popular music from the '60s, '70s and '80s, and a dash of MCU connectivity to draw all kinds of moviegoers in to watch a group of heroes who were D-list characters in the comics. Judging by the new Guardians of the Galaxy Vol. 2 preview, we can expect more of the same and then some come next summer.
