Though the writing can be criticized, overall it's very watchable. Very notable performance is given by Mackenzie Foy as young Murph. Amusingly, she somehow looks very alike Anne Hathaway who plays Brand.

You can pardon it taking liberties with physics. There is no enough fuel on Earth to deliver a spacecraft back from the zone with >0.99c escape velocity (and not enough fuel to slow it down for landing there, in the first place). The enormous time dilation coefficient dictates the escape velocity. But if it gets the plot moving, then OK.

I watched it in IMAX 70 mm film projection. IT SUCKED. There was a lot of shutter flicker on bright areas. These days, we don't see the flicker caused the projector shutter (obturator), because modern digital projectors mostly don't need them (though some older digital projectors with sequential colors may have some, but it would be mostly concealed). The image effective sharpness was never better than HD. The editing workflow seems to have been digital, because there was unsharp masking (digital sharpening) fringe always visible. There was AWFUL lot of grain in the picture.

Why do they still shoot film these days? Have they ever seen film and digital side by side? It's like 78rpm gramophone disc sounds compared to a CD. Does film grain, tinted colors, lousy sharpness make those old school cinematographers hard? If the movie were shot completely on modern digital cameras, it would have looked MUCH MUCH better.

Famous IMAX audio was too loud. The low frequency rumble was so big that it overdrives the ears and causes intermodulation, so that music and speech is heard with tremolo.
