A friend is struggling to remember a word. It was for a parody of X which is also a good example of X. For example a parody of westerns which is also a good western in its own right. There are some comedy bands who do parodies of various genres of music that are also good examples of their genres. He came across this word in a review he read some time, has a decent vocabulary and we've been through the obvious : burlesque etc. He thinks the exact meaning was something that was both a parody and a sincere example of the thing that it's parodying.
eta: I obviously haven't phrased myself well. An example he gave was the film "Isn't It Romantic" which parodies romantic comedies while still being a good romantic comedy. (tips hat to Mari-Lou) Another example might be Alberto y Lost Trios Paranoias whose song "Heads down no nonsense mindless boogie" - a parody of bands like Status Quo was really popular with Quo fans.
