Since we are in the midst of Dark Crisis I thought it would be interesting to see which cross over readers enjoyed the most.

It seems almost every DC event has it's detractors so I'm curious which ones people enjoy the most.

I've limited this to cross overs that spill over into the wider DCU and not events that are limited to just the character's titles. Sinestro Corps War was really just a GL event if it drew in characters from the wider DCU but Blackest Night really spilled over into the entire DCU so it does count as a DCU event.
