If your favorite MCU movies are the Guardians of the Galaxy movies then here are your comic book recommendations. I want to preface this with; the Guardians comics are nothing like their live action counterpart. In fact when my dad and I went to see it he was really not excited because the comics are very camp and goofy. But he was blown away by the movie and it became one of his favorites, so if you are experiencing Marvel in the reverse and taking comic recommendations off of the movies you might not experience the same love for the story. Especially if you are interested in origin stories. The further back you go into this team’s appearances the less familiar it gets.
Overall the Guardians of the Galaxy as a team is kind of all over the place, but the 2008 series really gave it some stability and consistency. The more recent stories bear a closer resemblance to the team that you know and love. That said the earlier stories are a fun read and I think they perfectly capture what comic books are at their core. They are a fun, light hearted experience and with that they do a very good job.
