Waxwork (Hickox, 1988) and Waxwork II: Lost in Time (Hickox, 1992). I guess that if you weren't around when these came out, they must feel really dated today. They are still fun films, the first one being vastly superior to the sequel, but the Bruce Campbell bit in part 2 is pretty over-the-top funny. The premise and original idea are great, and are pretext to create cool metafilms before it was overdone (for the first one at least, the second one is in itself overdone on all levels).
Problem #1 - Hickox is an ass and a very bad director. The pastiches of the first film are ok at best. The parodies of the second one are atrocious (only the The Haunting one has interesting formal elements, probably because he tries so hard to emulate Sam Raimi's style, without knowing how relevant it is to a The Haunting parody). His parodies only work on sets and costumes, he has no idea about film language. It either falls flat (his Dawn of the Dead) or has a little too much MTV (his Aliens). After the relative success of these two wax films, Hickox went on and ruined Hellraiser 3.
Problem #2 - Hickox is an ass and a very bad actors' director. At some point, you can't just blame the casting. Of course, the films being so 2nd degree, it's tough to play these parts seriously, but reality is they are just baddly written (the main actress, Hickox ex-girlfriend, refused to be part of the sequel, ok can't blame her, but that's no excuse to rewrite the character completely). Same for Galligan's character who is all over the map and you just can't get a hold of.
Problem #3 - Hickox is an ass and a fanboy. It's obvious that he is having a blast recreating parts of his favorite films/genres, and that's one thing that's pretty cool about these films. But apart from the premise, there's really very little original ideas left here. Borrowings (from Evil Dead 2, from Back the the Future 2, etc.) are so close to the original films, you have to wonder if they're weak allusions, weak parodies or plain plagiarism.
Problem #4 - I'm an ass and a nostalgic one at that. So I can't blast these films without feeling cheap. There's a lot of fun and a lot of love for cinema involved in these. And I'm a sucka for intertexutality, even when it's not very well done. So I'll still go with 6/10 and 5/10, just know that they're not completely worth that.
