I don't "get" Chinese humour, I never have and I likely never will. Given the tone of this film then, I was never going to rate it highly.

Some general is trapped at a ghost town, surrounded by 100,000 enemy troops; his son-in-law won't send troops since they'd be out-numbered anyway and, with the capital left undefended, the entire nation would fall. Illogically, the son decides to set off alone to rescue the general and his few fatigued surviving soldiers, stopping at a mining town along the way to con villagers into aiding him.
With 800 "warriors", they set off to face certain death... but that's okay, because, with wire fu, anything is possible!

Lacking anything remotely resembling a Marvel film's budget, the production values are very high, albeit, there are a few dodgy angles likely chosen to hide the shortage of funds.
Character development isn't needed and the acting is what one would expect for a slapstick Chinese action flick. Yeah, not my cup of tea at all. There were a few good ideas in there but, for me, they didn't really pay off.

So, now you know what to expect, you can check this out or skip it, depending on your tastes. I just wish someone had have reviewed this before I saw it so I'd have known not to have bothered.
