Surreal, i guess i have a few responses to that. i like to discuss symbolism because i spent too long in AP English writing essays about that sort of thing and now thats the way my brain works. i have been trained to ignore whats going on at the surface and delve into the subtext. and i dont think there's anything wrong with that. there are tons of references, metaphors, allusions, etc, that t and t have stuck in there on purpose for educated people to mull over.
And mostly, like you said, the obvious stuff is obvious, and therefore, mostly goes without having to bring up/discuss all the time, because there aren't too many opinions you can have about facts. the fact is, we already saw the Will/Elizabeth ending in movie 1. it was great, it was sweet, but we already had it. why would i wait through 2 more movies of endless depth and emotional journey to get the same ending?
i just cant imagine sitting around discussing how the ending we already got is probably where this is all leading, and all the metaphors/allusions/etc are just in there as macguffins. sorry.
