Predictable. Over-the-top. Silly. Contradictory (plot holes). Artistic dumbing down: so many moments could have been 'acted', instead of explained with dialog.
And yet, even with all those flaws it's 5/5 a good time. Go in to this expecting a popcorn "Hong Kong" (Taiwan now?) action flick, with lean storytelling and dumb humor and you'll have a good time. If you're expecting complex character arcs to expose a deeper truth about humanity and the universe, you may have a bad time.
