There aren't many filmmakers who are hard on themselves. Francis Coppola and Oliver Stone are two that come to mind who are very honest about their own films. Stone criticizes the special effects and the score and is hard on himself for a lack of experience, especially making films of this type (he wanted a psychological film, the producers wanted horror, hence the reshoots). As with most commentators he pauses a bit too much and constantly refers to how the effects could be done better now. And he has half a bad memory, he can't even remember doing the nude scenes! (Although he puts this down to being either high or drunk). He does talk about the many similarities to U-Turn, the improved effects work by Stan Winston and Tom Burman and places the film in a fascinating context, just after his Oscar win for Midnight Express and just before a five year directing slump (until Salvador) in which he pumped out several scripts, including Scarface and Year Of The Dragon.
