What I game "Willard" as a bonus on top of my rating, I cannot give to Ben as well, because everything done in "Ben" was already was done once in its predecessor. The big problem: The predecessor is better at it in all aspects:

The Acting was mediocre and I cannot point out any actor that was as interesting in their performance as where Bruce Davison or Ernest Borgnine. Also the characters motivation is really strange - knowing what has happened it is in no way conceivable that the boy hides the rat and even keeps the incredible dangerous looking "base" a secret, while his sister even covers for him?

Story is nothing special as well with no surprises what so ever. Also it seemed that there where a lot more special effects, the rats looked somehow off, when there where larger numbers of them. This is what a bad sequel looks like, and despite it being younger it feels like being the older one, with worse quality and production value.
