Matt Reifschneider’s review published on Letterboxd:
If you thought The Avengers had great banter and chemistry, then Guardians of the Galaxy will make you pee yourself a little. James Gunn goes epic with his space opera in the film, but his roots in genre filmmaking (horror, dark comedy) still freely float through the film. Truthfully, the only thing that was weak was the villain (again). Marvel needs to move away from stoic villains. Otherwise, this film was impressively executed.
I also think that James Gunn should remake The Ice Pirates. That's my big take away from this film.
