I'm a well read grad student who's bluntly honest about all things, although I try to be most honest about myself.
That is, Guardians of the Galaxy had a story arc that went beyond one issues. Guardians Team-up was one team-up per issue. Each had their charms, and this manages to intertwine one team-up per issue, but also has an overlying story arc. It has the best of both worlds, but means that you can't pick up three and really get it. You kinda have to read the first two issues.
Still, Angela guest stars in this one, and I love me some Angela.
And I'm running off, so short, short review.
