Interstellar was incredible. The visuals, the score, the acting, were all amazing. The plot is definitely one of the most original Ive seen in a while.
Most of the critic reviews have said that some bits are a little too unbelievable, but I have to disagree. Yes, there were some parts that were definitely in the "fi" part of sci-fi. But the thing is, Interstellar deals with concepts that we know very little about.
We have no idea what the 4th or 5th dimension is like, or what it would be like to go through a wormhole or a black hole. I dont think its fair to call something unbelievable, when we have absolutely no idea what WOULD be believable in those circumstances. Either way, excellent writing from the Nolan brothers. The visuals were outstanding, and will no doubt be nominated for an Oscar.
The performances were excellent, though nothing Oscar worthy, as is the case with most of Nolans films(The Dark Knight being the obvious exception). Hans Zimmers score was amazing and blended perfectly with the film. All in all, Interstellar is an excellent movie, which I personally think is Nolans most beautiful film to date.
