Past low effort video game movies? Borderlands just released. The budget got bigger, but I don't think there's an honest effort here.
Even more controversial, I assume, the Mario and Sonic movies are forgettable at best. I couldn't think of a way to make them more generic without dropping the theming entirely.
On the topic of Mario, how did Jack Black end up in the Minecraft movie? I haven't seen anyone else in there before, I think.
