Why do Star Trek and Star Wars fans think that all media must tie into a single, consistent continuity? Do Batman fans complain that Nolan's Dark Knight movies are consistent with the Burton Batman movies? And both movie versions don't stick with the continuity of Batman comics and TV shows (both live-action and animated).
Even the recent Amazing Spider-man doesn't tie in to the previous films, comics, and TV shows.
I like seeing new takes on classic stories. When universes become too big, it gets to be impossible to keep everything consistent. If Star Trek was one big canon between all media, there would never be any new five-year mission stories because the timeline is filled to capacity.
