Honestly, after watching it I can't see what the whole fuzz is about. Hard to judge any of that without context. It's the culmination of a romance plot, obviously it's going to stink when one hasn't experienced the whole development. Romeo & Juliet at the balcony is also corny when one only focuses on that one scene.
Seemed to me the delivery of that Morrigan was deliberate - maybe she's supposed to be the powerful, but socially awkward sorceress. *shrug*
Also, seems the dragon lady is voiced by Captain Janeway.
