The thing about the horror films of today is that it preys upon certain basic ideas we have about humanity. When you watch a horror film, particularly a scary horror film (because there are some that are not), you have to remember that what you are seeing is a reflection of us, the kinds of fears that we live with today on a daily basis. However, classic horror films tend to be about something else. They tend to be a reflection of a fear that we used to have once upon a time. A time long since passed even though there are many who lived in that time.
Making movies today of those types of genre requires an understanding of that concept and the ability to carry it out. A parody can sometimes go either way. The idea can be to reflect a current fear and do it in classic horror film style to evoke the nostalgia for that era, or it can be an attempt to do the opposite and use current horror film style with a classic fear to make fun of it. Either can be pretty effective if done well.
In the case of Attack of the Giant Vegetable Monsters, I am not entirely sure which they were going for. I am not even entirely sure what it is that the fear is trying to evoke. But in classic parody format they clearly understand the film genre they are making fun of. They understand the monster movie and they understand the kind of film genre that exists out there, and often times in a parody that can be more important than anything else. Because of that, I really liked the film in question. I thought it was one of the more entertaining movies that I have seen on the site and it had some great elements.
The animation was very simple but that goes with the setting and the era they are trying to invoke. Plus the little twist at the end, which I can say I was not really expecting definitely had me liking it even more. I say check it out below or find more on Film Annex.
