It's the best use of an inexpensive chuck roast or round. Pot Roast can be terrible dry mystery meat, or it can be OK. Pot Roast never looks very appealing, and should taste better than the pile of grey, well-overcooked meat looks.
Either way, it gets the family well-fed and meated-up. Kids need meat to grow their brains. I like this recipe because it has lots of my favorite root vegetables in it, parsnips, turnips.
Pot Roast is not a roast, it's braised. I call it Braised Beef and it has to be cooked until fork-tender.

Here's Alton Brown's version which we have made and is uniquely tangy.
A (tomato-free) Italian version: Stracotto
Seems like a good thing for crock pot cooking.
