Should I read Future's End?

If so, what's so important about it? What's the premise? I'm trying to catch up on issues that I've missed so I haven't had the money to buy any of the FE issues. Would it be fine if I just passed on them or should I try and get the FE issues as well?

it's a cool maxi-series, you might not have to since it takes place in the future, and by the end, they're probably gonna do something involving time travel to make sure things don't happen exactly like it, might lead into a sort of event(a new crisis?)
