I looovvveee Interstellar. That "No Time for Caution" sequence is the exact point in time that I granted Christopher Nolan apotheosis. Doesn't hurt that I'm a bit of a space geek too. It's as if Interstellar was made with marketing crosshairs aimed at me.
However, I think it's still in that "only time will tell" phase. Like Cameron's Avatar---mindblowing during it's time and for a few years after but now just mostly remembered for the implications of Na'vi anatomy and the lazily named unobtanium---Interstellar might yet be remembered more for the cheesy bits than its storytelling.
I still have very high hopes for it though! But I'm giving it maybe five more years, at least a decade. Fingers crossed!
