I would kind of a agree with you, but I think it is worth watching, if only for the lols. It is pretty bad, but thats what makes it worth seeing.
It is like the Mario Borther movie. Has almost nothing to do with the games and is incredibly bad, but that makes it worth watching because you can laugh at how bad it is and all the attempts at a connection to the games.
The same can be said here.
I went into this film under the assumption it was going to be bad and I enjoyed it because of that
