No, it's not really that bad. It's silly, and the last 15 or so minutes with the "evolution" crap is ridiculous (although TNG's "Genesis" is, if anything, worse), but there's some decent character work for Paris and some humour as well ("I've thought about having children. I've never thought of having them with you.") There are several worse episodes of Voyager (and of the other shows, for that matter).
