Before I go on, let me be clear: I don't need a ton of time travel in The Flash Season 4. But something that wouldn't hurt the new season is a visit into the future.
Barry only seems to get hate from the Speed Force when he goes BACK in time. But we did see him visit 2024 which seemed perfectly fine with the force.
Even though 2024 was grim and depressing because Iris was dead and Team Flash was broken. This year I want to see our speedsters visit a future that looks optimistic.
This could be a way to utilize Bart's presence on The Flash by showing us where he comes from.
