Loving and hating something at the same is part of lifting! It's exactly how I feel about the squat.
Bent over rows are all about rythm. Watch some bodybuilders doing them on youtube and you'll see that they move up and down quite a bit while they do them. You don't want to cheat as much as some of them do, but if you get your head bobbing up and down just a little as you do them they become much easier. As long as you focus on pulling with your elbows and not your hands and squeeze your shoulder blades together at the top you'll still get a great back workout.
