DC's LEGENDS OF TOMORROW has been, overall, a fun show to watch. The characters are a disparate bunch, their origins are slightly (okay, more than slightly) different than what we've seen in the comics, but for the most part it's been enjoyable to watch them band together and travel through the history of the DC universe (or the Arrowverse, specifically). We've seen them travel back to work with Jonah Hex and even the Justice Society of America.
Granted, the rules of time travel for our band of adventurers don't seem all that consistent. For instance, they're told by their founder, Rip Hunter (ARTHUR DARVILL) that they can never go to an event in time where they've already been, to avoid interacting with their other selves. This is something that could break time. This is also something The Flash does about every half-dozen episodes or so, but his actions never seem to cause a time-quake detectable by the Waverider.
