@matana I don't read comicbooks, but when there is a known joke, that there is no "first book to buy", you have a problem.
Noone likes reboots, because they are "micro reboots" where it still is in the same multiverse, only 1/20th of the usiverse is rebooted etc, and it still doesn't help you to begin, since you don't know how will it fit into the new universe.

Oneshots is another solution to the same issue, but they do need to build the connections eventually.
