Although I'm a fan of NTRG's previous productions, I'm going to hit this one for being substandard compared to earlier efforts. It feels to me as if the Dev phoned this one in.
First, the pace is rushed. A few more frames with a backstory would have been nice. The boyfriend appears to be mid 30s at least while the roommate is in college--or so we're told. The couple act and appear to be in a long term relationship, but the interaction with the roommate (how long have they been roommates) seems as if they just met.
Second, the roommate appears to be a caricature of Jerry Lewis in one of his 1950s movies. It doesn't work--at all.
Third, the boyfriend is hiding in a spot that even Helen Keller could see. Use a hidden cam, go outside and peek through a bush...somewhere else than where he's parked. Also, the excuse the BF gives to leave the room doesn't fit with time of day.
Fourth, the seduction is very much lacking in any form of eroticism. Clothes suddenly disappear. Little to no verbal communication. Again, too rushed.
Fifth, why add any sound effects when they don't match the scene (first set) or they are completely out of sync with the animation (second set)? It would have taken 30 minutes tops to drop the frames (why PNG I don't know...but anyway) into an NLE, drop the audio track on top, match the sync then render. If you can't do it well, don't do it.
