7. The Elder Scrolls V: Skyrim
Skyrim completely blew Elder Scrolls fans out of the water in November 2011 when it was released by Bethesda. The art, story, and DLC were all top notch, and the game won roughly 20 awards.
Why it would make a terrible film: Too much to cover. Taking all character creation possibilities out of the equation, we're still left with a long plot riddled with side quests that could be incorporated. How many of our characters accidentally became vampires that went in search of a cure? Who loved the Dawnguard and Dragonborn DLCs? Fans would love to see elements such as these incorporated into a Skyrim film, but with the basic plot as long as it is, it's unlikely that they will be satisfied by whatever the potential screenwriters come up with. The only viable solution would be a franchise with multiple films. The fault in that plan is that it banks on fans staying interested long enough to complete the series, and on writers distributing plot and sub-plot elements well enough to make the films flow and keep viewers engaged. Even if all of that were to pan out properly, possibly the most important hurdle is left unanswered: character species and alignment, which brings us to poor film choice number five...
