Seems to me like we're wandering away from the OT here. The way I see it, the timeline doesn't affect the quality of the movies. You can tell good, bad, or mixed STAR TREK stories in either
timeline. Or, maybe someday, another one.
STAR TREK is bigger than "canon" or "continuity." Merely setting a new movie or TV series in any particular continuity is no guarantee of quality--and is not necessarily a virtue in its own right. Execution matters more than the (relatively) trivial matter of what timeline it's set in.
