Good start, but then it gets ruined

It isn't all that great, actually. Really cheesy and very predicable of how certain scenes are gonna turn play out. However, I guess that's the charm of it all, because I would consider this one of my guilty pleasures.

if their story seems completely bonkers, almost like a feverish work of fiction, you ain't heard nothing yet.

Great story, amazing characters, superb action, enthralling cinematography. Yes, this is something I am glad I spent money on.
