Basic point is that if your taxes are simple enough to just say that yep these numbers square with the few pieces of paper I received in the mail, filling out a return is maybe 30 minutes work.
I would say (as someone whose taxes will never take less than several hours) that those 30 minutes are about 28 minutes too many.
That was also the year when they intentionally broke the withholding calculations so that people end up owing a big unpredictable amount of money when they file, are more likely to be fined for it, etc.
