I watched this on IMAX, but could have as well watched it on a normal screen. Many so called Sci-fi nuts will not like my review here, but I have to be honest. In the movie, a combination of bad acting, cliché situations and melodrama masks, the otherwise beautiful representation of the cosmos. There is no doubt behind the effort put in representing the wormhole or the Gargantua or the sequence of the spacecraft traveling through the cosmos, but it was not supported with good acting and strong science fiction script (even fiction can have nice theories made into beautiful script). Some of the scenes were laughable (like "that will work" - about the so called novel white-board plan by Cooper or Cooper saying "Love is quantifiable" or smth like that) The attempt at philosophy , human values or thought, was at the best mediocre. Also Christopher Nolan could not resist bringing in the cliché 'Hero saving the day' part.

Interstellar is being often compared with 2001:A Space Odyssey, but other than using 'Organ music' during some scenes it does not come any closer (I am aware that 2001:A Space Odyssey uses Classical and Orchestra pieces of the classic masters, not just Organ music)

In the end I am very relieved that, all the 'They' in the movie did not lead to 'God', to that extent Mr. Nolan has kept it within the bounds of Science and reason.

That said; here are some of the good parts: TARS the robot, Wormhole, Gargantuan, Space travel, representation of cosmos and black-hole, alien planets and some of the background music.

In conclusion: Interstellar could have been a pure Sci-fi movie or an action Blockbuster or a philosophical one or just even a mega budget tech show, but it tried to be all of this at once and ended being none.
