5) More Crossovers
In the tradition of annual comic book events, The Flash and its sister show Arrow have begun to link with scheduled team-ups each season which are undoubtedly highlights of both programs. While the suggestion of more crossovers was already made in a companion piece about season four of Arrow, there are a few more points worth bearing in mind here.
Watching the newly christened Green Arrow and Flash work alongside the Legends of Tomorrow could be one of the best things seen yet on a CW show, assuming the budget allows for that much super heroic goodness on screen at once. If this does occur though, the writers will need to ensure that the crossovers continue to be believable and that any conflict between the heroes isn’t crowbarred in purely for the sake of it.
Another overlooked advantage of this shared universe is the smaller crossovers that involve supporting cast members such as Quentin Lance and Cisco Ramon. Each successive guest appearance makes the links between both shows more believable, while also rewarding loyal audiences who tune into both The Flash and Arrow. If Arrow’s too busy to help Barry out, wouldn’t it be great to see Thea swing by in her new Red Arrow costume and lend a hand?
