Would two whole rolls of aluminum foil and suran wrap make a badass capacitor?
Probably not.
Commercial capacitor designers carefully balance the breakdown voltage and dielectric properties of the insulators between the plates when making a capacitor for a specific type of application. One of the goals is to make each layer as thin and uniform as possible to maximize that capacitance. You then want those layers to be as close as possible.
Aluminum electrolytic capacitors achieve high capacitance by shrinking the space between the plates to molecular levels by using a thin layer of aluminum oxide as the insulator on one plate. The electrolyte is a conductive liquid that effectively allows the other plate to be closely coupled to the insulating layer. The alumimum layers themselves are made as thin as possible.
A metalized film capacitor (polyester or Mylar) is made by depositing a thin layer of metal on a layer of plastic film with a carefully controlled thickness. A thicker film will result in a higher voltage rating while a thinner film will give you a higher capacitance. Other plastics are used when other tightly controlled characteristics are more inportant than simply achieving the highest voltage or capacitance in the smallest possible space. With the proper manufacturing processes, you might reasonably expect to realize a capacitor with about 5% or less of the capacitance that could be had from a similarily sized electrolytic.
Polyethylene is the primary plastic used for making Saran Wrap. It is unknown whether there are other ingredients that could compromise it's insulative properties or even what the breakdown voltage might be. Polyethyene is one of those other plastics that sometimes finds use in specialty capacitors.
Other than as a science fair project, rolling your own capacitor from commonly available materials is not a practical undertaking. It is unlikely to give you a high quality capacitor with known characteristics and it certainly won't be cost effective.
