This event will be the first time that shows other than Supergirl directly deal with aliens, so we should probably expect some comedy along with all the fighting.
The Dominators may be an evil race bent on destruction, but that doesn’t mean we can’t get some laughs out of characters’ reactions to them.
Those of us who tune in for all of it may need Friday as a day of rest to come down from all the action.
The crossover will start on Supergirl in its regular Monday night slot before moving to The Flash on Tuesday, Arrow on Wednesday, and it’ll then come to what sounds like an epic climax on Legends of Tomorrow on Thursday.
