Watched for a second time this week (after twenty years), and was quite under-whelmed. In fact it slightly put me off David Lynch! So your help is badly needed.
Not that it was THAT bad, it was quite fun. But it has so many familiar Lynch tropes, themes and mannerisms handled much more blatantly, it was almost like a homage or rip-off.
One thing that did excite me was that it could serve as a rosetta-stone to understand his language, like watching a drunk magician and catching a glimpse behind the curtain at how the trick is done.
