Which would have more people upset? Warp Drive fast enough to get them outside the Galaxy in such a short period of time (As in TOS)...
Such two-dimensional thinking... Do you believe the galaxy is spherical, or a flat spiral? In which direction is it stated that the Enterprise was traveling? Is the barrier only around the edge? Or the entire galaxy - above, below and around? Think about it.
In TOS, it was represented as a ribbon around the galaxy. Doesn't matter what direction you leave the Galaxy, you'd still have to go awfully damned fast to do it in a week or two from Federation Space.

Where are we going? And why are we in this Handbasket?
