I rather enjoyed the movie and may read the book some time when I can spare the time. The one part that was most unbelievable for me, however, was the cracked helmet scene and the emergency patch job with good old duct tape. Maybe the duct tape would have worked depending on the pressure, but a glass helmet? Seriously?? Hasn’t Hollywood heard that Plexiglass doesn’t crack? Even auto glass is laminated and has a plastic sheet in between the layers to keep it from cracking in accidents. It will craze but it won’t crack into pieces larger than a pea. We’ve had that since World War 1.
