I haven't seen the movies but I thought the 2008 series of Guardians of the Galaxy would be a cool comic to start reading. I read the first issue and although I am not confused about what went on, I feel as though there are things that I am missing as to the backstory of some of the characters and some of the conflicts they were in right before the 2008 series.
What are the things that I should know to provide myself with the best reading experience for this series. I feel like I will enjoy it, but I think it would be better if I understood the importance of characters like Nova (if he is important in the series) and the significance of Phalanx/Thanos. I would prefer not having to read an entire serious to be caught up, but if it is the only way to get the information then I'll have to.
