AB2012: I can't say I'm excited. Bioshock oozed atmosphere because of that feeling of lonely abandonment under the sea other than one 'friendly' guy at the end of a radio. Bioshock Infinite was good but didn't have anywhere near the same impact as the original precisely because it was a fully populated with everyone lazing about care-free. The problem with "video game movies" is they usually take 20 hours of content and squash it down to 2hrs by stripping out the same "boring" stuff like wandering around an abandoned city completely alone that's half of what builds the slow-burning tension in the first place, and simply replace it with action sequences / drama loosely based on the plot. I also wouldn't want to watch a 2hr Deus Ex movie for the same reason.
I actually think from a story standpoint, infinite would make a better movie than Bioshock. The twist is based on the character so viewers can relate to it far more than the impact of the twist in Bioshock. I agree that a tv series would be far better than a movie although the Witcher is not a great example imo. Writers just making up their own lore and changes so the politics of the writers is unfortunately important.
Little side note but Im also starting to feel that movies arnt really a good story telling medium anymore thanks to streaming. Before, it was laborious to watch a full tv show but with streaming, people can easily access and binge watch multiple episodes. CGI and special effects costs have also gone down and could be afforded by top studios (see GoT).
I do think action movies, rom coms and other short stories or stupid fun storiesa would do well in a movie format but for a proper long-form narrative, tv series is the way to go.
