Because I noticed too many contradictions with canon and when it came to stuff from the Forerunner Saga too many things that just didn't really fit in Halo or belong in the series for whatever reason (either not fitting the way the genre was executed or the themes, and so on). And the writing in Halo 4 felt rather simplistic to me and like the new characters weren't very well-developed or written. I think Halo 4 (and the rest of 343i's work with the story) probably would have been just fine if it was the start of its own, new IP/series, at the worst it would have simply been average and not really any better or worse than most of the games and series out there these days, it's mostly as a [i]Halo[/i] game and part of the series that it's particularly bad or insufferable...so yeah, if it were something standalone and the start of a new story that had nothing to do with Halo, I'd have absolutely no problem with it whatsoever. I'm not sure whether it'd have been a series I'd like or one that I'd enjoy, but I wouldn't actually have any problems with it at all.
