The tie-ins are bad DC marketing bullshit, and "\'s are appropriate. Nothing without the name Batman written by Grant Morrison has anything to do with RIP.
To understand RIP you need to read every single Batman issue he\'s ever written...twice. Its one big run and should be treated as such.
Yes All-Star Superman is extremely good. It ends sometimes soon with issue 12 and its the best Superman story ever.
Action Comics 866 is an extremely good spot to start reading the in continuity book though. So far its three issues in, and its almost as good as All-Star which I didn\'t think was possible.
