Over the past couple of years I've tried a couple of times to get into DC comics and it hasn't worked out.
I tried reading Batman R.I.P. after hearing all of the critical acclaim, and found the plot wasn't remotely intended for new readers.
More recently, I picked up the JMS runs of Super Man and Wonder Woman. With Super Man, the shift in writers and tone really limited my enjoyment of the series, and not much was happening anyway. For Wonder Woman, I feel like I'm still waiting for a reveal, without even knowing what I don't currently know. Without knowing the other versions of the character, it feels like I'm reading about random Amazonians dying, and some mythological villains without any motivation that I'm aware of. In both cases I can't tell if I just don't know enough about the characters to appreciate the series, or if the writing just hasn't been clear enough for me.
So I'm asking, as someone who only knows the pop culture version of DC characters (toys, movies, posters), where should one start if one wants to pick up DC?
