While I do love this movie a lot, it does have a few major flaws. The film has rules for these creatures, but not only do the characters break the rules, but the film does too. The first rule is to keep them away from light, which is done accurately, except for the scene when the Gremlins are smoking. If they're afraid of bright lights, and are extremely afraid of a lit match, how are they able to light the cigarettes that they're smoking? Second rule, don't get it wet, or it will multiply! How are they able to drink beer, and stand on Snow without multiplying? Does it have to be pure water? It seems that way, but the film never really explains it. Final rule, DON'T FEED IT AFTER MIDNIGHT! Plenty of critics have bashed that rule since it's always after Midnight, and while it doesn't bother me, my only question is WHEN IS IT OK TO FEED THEM? I assume it's around Daylight, but it's never really explained. While these are big flaws, I personally can't help but overlook them, since the film is so entertainingly awesome!
Finally, we move on to the human characters. Zach Galligan does a fine job at playing our main character, and does a natural job at interacting with all the characters in the movie, especially with Gizmo. His love interest Kate (Phoebe Cates) outside of her powerful and sadistic monologue about her back story with Santa and Christmas, she's pretty boring and bland. Hoyt Anxton as the Father, is a really fun character and performance, and seeing the many inventions he makes that fail is endlessly funny. Frances Lee McCain as the Mother is not only really natural at playing the character, but seeing her take out the Grermlins in the Kitchen is one of the best scenes in the movie! And Keye Luke as the wise old man who owns Gizmo, gives a really great performance, and despite only seeing him the first scene and last scene of the movie, he still manages to leave a really big impression on you. There are many other characters to talk about like Billy's friend; the teacher that studies the Mogwais; the next door neighbors the Futtermans; and the ignorant idiot cops who are just as fun and amusing as the Gremlins are, but you'd be reading this for awhile. I will say that my favorite out of the supporting characters is the nasty old woman Mrs. Ruby Deagle played by Polly Holliday, who is so unlikable and mean as some like Scrooge or old man Potter, that you pray for the Gremlins to get her at some point in the movie.
While some of the film's logic doesn't make sense, as well as being a little too dark, heavy, and tense for kids, it's still a really good movie. It's entertaining from beginning to end; the characters are all fun and memorable; the effects for the Gremlins are cool; the Gremlin Gizmo is highly adorable; and the Gremlins themselves have the perfect mix of being fun and scary at the same time.
