Memorial is vile and I completely disagree with Janeway's decision and yet is a classic Trek ethical dilemma and not boring.
Even though I completely disagree with Janeway's decision at the episode's end, Memorial is actually one of my favorites of VOY. It actually takes the four most under-utilized characters on the show (Kim, Chakotay, Neelix and Paris) and lets them carry the episode. And the scene where Neelix protects Naomi from his hallucinations is very good, IMHO.
