Reasons why this was the best of all the SNL-based movies

1.) Dan Aykroyd, 'nuff said.
2.) Great supporting cast with good acting and good on-screen chemistry between the characters.
3.) Very good use of SNL alumni from prior to 1993.
4.) Very funny.
5.) Has heart and centers around family, even a weird, alien one.
6.) Memorable scenes and quotes.
7.) A great look at building on the Remulakian culture, thanks to Dan Aykroyd being given space to develop his aliens better.
8.) Decent, okay special-effects (for the time this movie was made).
9.) A fascinating look at how aliens would adapt to our culture after being stranded on earth, with hilarious results.
10.) A chance to see Beldar and Prymatt's homeworld of Remulak and what it was like.
11.) A memorable arena scene involving fighting an alien monster (with an awesomely hilarious resolution that only Dan Aykroyd could have come up with).
12.) A happy ending.
13.) Great use of pop culture music for the time.
14.) Hilarious use of alien vocabulary from the Remulakian language.
