For people who are bashing DC launching some events including the latest "Dark Crisis". I may have an unpopular opinion but I think I like DC event crossover and here are various why I do so:
1) It's the only chance we get to see C-Listed Superheroes taking some actions and involve in the event.
2) Almost everyone in the DCU involves since it's a crossover event. The more the merrier.
3) The crossover event is tied to one big story along with its tie-in that tells the whole story. (Depends on which ties-in is required or options to read)
4) Without event and only go back to the basic DCU. You may only get to buy mostly A-listed superheroes book run. There is a low chance we get to see C-listed superheroes much often in a normal issue.
