It is, did you see it yet ? So much better than that average ending to Batman trilogy, and that remake of Superman (note to Nolan : stop making comic book movies and get back to your own ideas). If only more Hollywood blockbusters were this interesting and full of ideas.
Nolan back on form, good acting (sure McCounaghey is good, as is Caine but I thought Murphy steals the movie. Hathaway is overrated. Nice twist midway), a gripping story with elements of multidimensional universe, black holes and time/space travel. Only minuses were
the humour yapping robots and in the ending in I missed his son : do we assume he's dead since women tend to live longer ? Also, with all the years of his work on getting back to her, only to get "parents should not bury their children" and "go away, I have my kids here" ? I assumed both Cooper and TARS would get anihilated in the black hole while Brand would find a future home for humans but unable to contact anyone.
