To a certain film critic, hijinks of the alien behavior may seem over-the-top, but I'd argue this is the exact kind of thing that differentiates Resident Alien from other, conventional, boring extraterrestrial film/show genre. If there are aliens in the universe, why would aliens have two feet and two hands like humans? Why would their ethics be similar to ours? Baby alien fight scene with the Cats In The Cradle in the background was one of the most hilarious scenes this season.
But the fact that an alien learning human ethics is exactly why this show is still going strong in its 3rd season. Particularly the therapy scene and a reference to another therapy scene from another episode:
When I snap my fingers...
You will wake up...
And you will remember...
EVERYTHING.
