Ok, so, let's take The Mask, as funny, enjoyable film with great performances and fun silliness. Then let's take away every single good performance and everything worthwhile, add copious amounts of unnecessary mythology and plastic hair and crappy CGI and then you've got Son of the Mask
Let's start of simple. Our main hero, The Mask, is no longer portrayed by the likeable Stanley Ipkiss (Jim Carrey) but the somewhat annoying and not at all exciting Tim Avery. (Jamie Kennedy) Now, I like Kennedy in his previous work, but this, it's just not the same, the way he portrays The Mask is not at all how it has ever been before, Comic, Movie, TV, or video games, it's this weird mash up of a wax Conan O'Brian and the Burger King guy, with a terrible Elvis like voice. Our once likeable lead starts off with a terrible dance number, putting the song "You're just to good to be true" Into Dance, country and other terrible versions all while using a zoom lens basically the entire time.
The Mask then has sex with Tim Avery's wife, and then she has a baby which is not truly Avery's, but the Mask's, or Loki's or whatever. The next hour or so is basically close up shots of Avery being scared while a sometimes real sometimes terrible CGI baby tries to put him into a mental hospital for what seems to be for no reason. The baby may feel that he's not his real dad, and that the mask is or something I don't know, but then he ends up randomly changing his mind and deciding he loves him at the end.
Also, while Avery is not wearing the mask (Which is the majority of the film, what's even the point) the dog is, which is a terrible re-hash of a joke from the first where the dog found the mask and started hurting BAD GUYS, and in this one, the dog tries to kill THE BABY. Why? Well this theory is a little more clear as the dog feels like he isn't getting enough attention but still, this movie relies way too much on it's bad CGI as that's really all the 2nd act is, that and Loki (Alan Cumming) running around looking for his mask wearing unsettling costumes.
That's another thing. This movie is quite unsettling to children. A dog's eyeballs literally pop out and for about 10 seconds the dog has empty eye sockets. A man's face is taken off his body. A baby's face randomly changes into a scarier one, the movie's inappropriate for kids, and the first films audience is 13 and higher and wouldn't be interested, so who's the audience? No one. No one wants this film. It just needs to go join the other terrible sequel corner. The plot has potential but it's taken no where because they want to entertain us with bombastic frantic absolutely unnecessary CGI effects and some reaaaally bad acting at times. (See Steven Wright) Possibly if they stuck with the premise but maybe had, hmm, a better script, Jim Carrey, any funny scene, less Norse shit, and better CGI, it might have been a good film, but... unfortunately, it isn't. at all. But I do give it credit for making me at least smile like, once. That's it. That's the half a star.
