so i have been reading the Brightest day stuff (up to issue 7 in the actual Brightest Day books and all of the tie-ins up to that point) so i was just wondering: do i need to read the tie-ins? I read the tie-ins for Blackest Night and thought they were ok and i have not been liking the Brightest Day ones. if i just skip over them and read the main series of books will i miss a lot or can i get away with it.

at this point you do not need to read any of the tie-ins, though there is reference. Green Arrow i would say is the best of anything to read that directly deals with the brightest day. the others are just good reads in general.

i have been liking the Green Arrow, The Flash and Birds of Prey. the JLA, Titans and Generation Lost stuff i just havent been able to get into

Yeah, none of the tie ins are all that important from what I've read.

Just like any tie-ins...a limited amount of importance to the actual story going on.  Still, many of the tie-ins are good stories, like the Endrun story with Birds of Prey, and some are relevant to current goings-on in stories, like the Dark Things story with the JLA/JSA crossover.  Then of course there's the "unofficial tie-ins" with regard to Booster Gold and Power Girl and the Justice League: Generation Lost story.  And then there's the one ridiculous crossover that has absolutely NOTHING to do with Brightest day, and that's the Nucleus story that began with the Brightest Day: Atom special.  Truth is from what I know, the bare essentials of what you need are in the actual Brightest Day volume, after that its just stuff of marginal importance.
