I can barely even remember what happened in the original show. Even when Heroes was enjoyable on its original run it was hardly the most memorable show.
Yeah, they were very much about destiny and a messiah " save the cheerleader, save the world" sort of thing - although at least the current iteration of the show has much tighter plotlines and actually is about saving the world.
I think the problem with Heroes, season 1 (because subsequent seasons were just a mess) was that they were trying to work out what the show was about while as they went along - so the final product was good, but not great.
The original (the first season) was good, but suffered from the same problems that LOST, did - too many characters, too many storylines that went nowhere (until the writers started tidying it all up around season 4, but by then the resolutions they wrote weren't all that satisfying), and of course time-travel.
Nobody seems to be able to get time-travel right (which is a bit much for me to say, as nobody really knows how travelling through time and changing the past would work out in reality) but at least having a consistent approach to time travel would be good - I don't care if it doesn't really make sense.
I mean, I love the Flash tv show, but they've absolutely buggered up time-travel and its consequences.
