    Okay, I watched the film last night in 3D. I will try not to spoil it for those that haven't seen it.

    The Positives:
    1. Visually stimulating.
    2. Decent suspension of disbelief.
    3. Better than Prometheus: I've come to really appreciate how much of the science Stanley Kurbrick got right in 2001: Space Odyssey.

    The Negatives:
    1. Wrong Title - should have been named Orbital Dynamics or Dr. Ryan has a really bad day in Micro-Gravity.
    2. Roving Bands of debris - To my understanding, most man-made satellites objects do not share the same exact orbit of Earth, so astronauts running into the same debris multiple times (multiple orbits of planet, 90 minute orbit) while moving to lower orbits seems unlikely. I could be wrong on this, it just seems odd.
    3. Re-entry (can't say more without spoiling the movie)
    4. Physical Strength - Not sure how to phrase this, but here goes: If a human spends 1-2 weeks (assumption on my part) in micro-gravity how much muscle strength do they lose (When you see the movie, this issue will make more sense)?

    I'm still waiting on Netflix for this movie and it could be awhile. The Netflix has it rated at 4 and 1/3 stars out of 5 which is very good from my POV. The description below.

    Gravity

    2013 PG-13

    As a medical engineer on her first shuttle mission embarks on a space walk with a seasoned astronaut, debris strikes their craft and destroys it -- leaving the two floating through space tethered together, with no connection to Earth.

    Cast: Sandra Bullock, George Clooney

    Director: Alfonso Cuarón

    Genres: Sci-Fi & Fantasy, Sci-Fi Dramas, Sci-Fi Thrillers, Blu-ray

    This movie is: Suspenseful, Emotional

    Format: availability date unknown
    ================================================== =====

    First Netflix review

    The space elements are exceptional. Alfonso Cuarón's perspective of space is just mesmerizing. Sometimes it's the little things like the reflection in someone's helmet or taking in the view amongst all of the destruction that wind up impressing you. The silence is deafening. Space in film has never felt so quiet and haunting. The carnage caused by the debris is also astonishing. Not only is it a wonder to watch unfold, but it's amazing to see anyone emerge unscathed from such devastation. The one issue may not be a dilemma for everyone. Sandra Bullock's Ryan Stone makes this really heartfelt speech about where she comes from and her daughter pretty early on. It's extremely emotional and character defining. Needless to say, it's effective and memorable. What nearly ruins it though is that Stone tries to make another speech just like it in the final moments of the film and it seems completely corny in comparison. Up to a certain point, it works just fine but the whole "it's been one hell of a ride" part of it just debunks the whole thing and throws it into lame territory. "Gravity" practically redefines the space genre with its dizzying outlook of space, stunning cinematography, and the overwhelming sensation of being utterly alone. The sense of helplessness in "Gravity" is unlike anything you've ever experienced in a film before; an endless struggle to survive only heightened by the film's excellent 3D effects.

    Spoiler alert - do not read if you don't want spoilers.

    I thought the title appropriate, since gravity provides the reason that the protagonist must act fast to save her life.

    Roving Bands of debris - To my understanding, most man-made satellites objects do not share the same exact orbit of Earth, so astronauts running into the same debris multiple times (multiple orbits of planet, 90 minute orbit) while moving to lower orbits seems unlikely.

    It is unlikely. However:

    1) If the collision as described in the movie occurred it would be like shooting a shotgun at a cruise ship half a mile away. Your aim doesn't have to be very good; there would be debris heading in a pretty wide spread.

    2) If any of the debris did intersect with another object in orbit, and it was in even close to a similar orbit, you would tend to re-encounter it every 90 minutes. (45 minutes if it's retrograde.)

    3) They did not make any significant delta-V changes, so they stayed in essentially the same orbit.

    Physical Strength - Not sure how to phrase this, but here goes: If a human spends 1-2 weeks (assumption on my part) in micro-gravity how much muscle strength do they lose (When you see the movie, this issue will make more sense)?
    They lose a lot. The only time this seemed to contradict what happened in the movie was in the last 30 seconds when she stood up. Until that point she did seem pretty weak.

    Are all hatch covers designed to violently explode open in space? If so then by holding onto the handle of one using a gloved hand would astronauts be able to hang on, not once, not twice but several times (I lost count)?

    All that belongs to human understanding, in this deep ignorance and obscurity, is to be skeptical, or at least cautious; and not to admit of any hypothesis, whatsoever; much less, of any which is supported by no appearance of probability...Hume

    No, hatch covers made for the ISS have no such explosive device on them nor the space shuttle.

    Loved it - brilliant entertainment. Didn't think people could get in and out of space suits that quick and alone though. Also thought it was the wrong title but I guess its what got her home really.
