This show is very quirky and the comedy takes some getting used to but you quickly wanna see more and more.
Harry is a quirky, funny, alien who's taken the place of what i am guessing was not a good person and he's made him good in a very strange way.
Now, this show definitely isn't for everyone. You have to have a certain type of sense of humor to like this show.
There is an element of "I've learned something today" in this series and an element that makes the heart feel good about being human.
They've got nice guest stars and that adds an element of spice to the show. Seeing Linda Hamilton was a nice addon.
This show, without a doubt, tends to evolve over time and it doesn't soley focus on the main character, it tends to move over to the female's relationships more than usual.
I dunno, there may be more to say.... I'm currently in season 3.
