I loved the Borderlands games, they were perfect in nearly every way from the writing, to the characters, the comedy, the scenes, etc etc.
This movie takes everything good about the games, ignores them, and then makes them horrid.
The casting choices: as everyone is saying, who in their right mind came up with this cast? They do not fit ANY of the characters at all. Not a single actor belongs here let alone attempts to even act for the entire movie. The only one who put an iota of effort was Jack Black.
Pacing: Awful in every. single. way.
Story/Plot: ??????? Nonsensical, utter garbage.
Overall: DO NOT WATCH IT! If you want a good borderlands experience, either play the games, or just watch the cutscenes on YouTube.
