So one of the best parts about Lost was formulating wild
theories about what was going on on the Island. Was it a
parallel reality? Unstuck in time? Purgatory? And the creators
promised us that, by the end of the series, we'd know.  Well,
they were right, but we wish they hadn't told us. The massive
hit ABC show totally went off the rails in the last season,
perpetrating all of its worst tendencies (New characters nobody
cares about! Huge leaps in logic!) and adding one horrible new
one.  The whole reason for everything was a magic cave like
something out of Land Of The Lost. I can't even begin to express
how shoddy the whole wrapup was.
