Not so bad until the escape... (spoiler)
Not a great movie, but watchable and untertaining until the 'hero' escape... and come to the vilain's lair alone, without a plan or a weapon...
Well, you can do better when you're a trained soldier, or an average humain being with half a brain... (pun intended)
... The end is quite stupid and predictable from this point.
Vilain got Matsterplan (TM).
Vilain tells MasterPlan (TM) while posing and dancing. (quite funny, actually)
Vilain tries to kill the hero with a complicated method for no particular reason.
Then vilain fails stupidly.
Happy ending.
(Audience violently vomiting)
The last part is a waste of an interesting idea and development. Too bad.
