This seems interesting.
While this was a nice parody trailer and the comedy that was there was fun, personally I'd prefer if you were to do a more dark and serious thing.
As for this trailer itself, it was decent. Like I already said, the humor was good. That vibrator joke made me chuckle but was predictable. The models and scenery looked nice, though the animation looks really awkward. I'm not sure how it would be fixed since I don't know a lot about 3D animation, but some movements look robotic and others just look... well I'm not sure how they look but it feels awkward. The lip movements also didn't look too convincing.
I had mixed feelings about the voice acting. There was something about the female voice actors and how they sounded that just didn't sound right to me. It's not that distracting though.
Either way, I'd watch it, and I say go for it. I'd just prefer a more serious approach :p
