That the last episode in the Xiao Xiao series should be relegated to being an advertisement for a shopping mall is strange, and kinda sad.
A series that had such promise, and often delivered on its fantastic fighting set pieces being reduced to what is basically a rehash of Xiao Xiao 3 in a shopping centre. Don't get me wrong, the animation here is impressive as always, with the fight scenes being quite well choreographed and some good 3D effects at the end.
But this is overall one of the weaker entries in the series and the fact that it is the last of the series, still not resolving the story of two earlier Xiao Xiao movies is very disappointing. A shame really
