The problem with this one is that it's just so AVERAGE.
The plot: nothing special; action: average; camera work: competent. The actors do their jobs but their roles aren't so demanding and their characters simply aren't very memorable.

There is a massive demand for Korean content at the moment and, of course, it creates opportunities - which is always great - but it also means that more duds are going to seep through the cracks.

Oh, I need to use 500 characters and I really wanted to keep this short and sweet...
