It's fun to have a companion around to keep you from getting lonely out in the wasteland, but do they have to be so freaking dumb? Hell, even for the standards of a dog some of this stuff is pretty unforgivable: companions will stop following you, get snagged in objects, walk around in circles and run headlong into enemy gunfire rather than take up a strategic position. This is all pretty basic stuff that should've been caught pre-release (especially the latter point), but most depressingly it makes having a companion around more of a chore if anything. Needing to babysit a sub-functional character can be immensely frustrating, which is a shame considering how charming some of them can be (especially Dogmeat and Nick Valentine).
