IMHO, the only "hopeless interior" is one where the modeler doesn't have either the willingness to develop their modeling skills, or more importantly, the patience required.
Then again, I'm biased since many of my all-time favorites are the 1:48 Monogram aircraft kits from the 60's.
Personally, I get a lot more satisfaction by doing some research on the subject and then using plastic sheet, wire and other miscellaneous bits (old watch parts, etc), to detail cockpits.
