It wasn't a bad movie, but it didn't make a lot of sense in places.
If you're going to use your suit as a jet, then make damn sure the thrust goes through your center of mass. Sticking your hand out to your side would just cause you to pinwheel.
The evacuation happened when the MAV was in danger of tipping due to wind forces... Yet NASA lands MAVs years ahead of their intended mission, and just kinda hopes they're still upright when needed?
I think the actual force that "wind" on Mars can generate has been adequately discussed elsewhere.
If your MAV is tumbling out of control, then nuts and bolts are not going to be rattling around randomly. They're going to settle due to the rotation acting as a centrifuge.
If you don't have enough fuel to slow down, catch your astronaut, and then re-accelerate, then maybe blowing a hole in your ship to "slow down" is a bad idea. Just sayin'. Particularly if you have a rotating torus attached to your ship, AND IT"S STILL ROTATING DURING MANEUVERS!
If you're tethered, and you get stopped by the tether, what trained astronaut is going to just hit the thrust again in the hopes of magically stretching the tether another 100 meters?
If you and another astronaut are tethered and rotating, then you will only speed your rotation by shortening the distance between you. Anyone who has seen a figure skater knows this.
OK, end of rant. I'm just sick of hearing about how accurate the science is.
