While people still treat Prometheus as some sort of cinematic war crime, on second appraisal it's not that bad and I'd bump the film score up to a 7/10. The dumb stuff is still dumb and Holloway is a complete tool and thus his death isn't really that much of a loss (spoiler alert!), but the overall slick style, Fassbender's performance and Ridley Scott's ability to still throw down a tense scene like the auto-doc alien extraction sequence make it a missed opportunity more than a complete failure.
More problematic is this Blu-ray release which along with Life of Pi saw Fox putting some of the special features exclusively on the 3D version release, forcing people to either buy a version they may not even have the capability or interest in watching in order to get all the extras or doing without. While Life of Pi's omitted extras appear to be minor, the 4-disc collector's edition I bought (and sold off the 3D disc to a friend) came with an amazing disc of extras with a production documentary and tons of goodies which were actually better than the movie itself. The problem is that it appears to have gone out of print - it lists on Amazon for over $350(!!!) and while Best Buy lists it for $20, it's not actually available.
If you're not an extras fiend like me, then the basic disc is a good pickup for $10 or less; the transfer and audio are pristine and the movie doesn't totally blow despite being full of bonehead actions which led to Cinema Sins coining the "Prometheus School For Running Away From Things" to describe any time people aren't trying to dodge to the side.
Score: Collector's Edition - 8.5/10. Buy it if you can find it. Regular Edition - 7/10. Buy it cheap.
