This movie is internationally known as "The Eight Hundred". It is based on true events during the Japanese invasion of Shanghai, whereby the focus is put on the famous "Defense of the Sihang Warehouse".
The "Sihang Warehouse" is located directly next to the foreign concession of Shanghai. This means that all attacks by the Japanse army on the soldiers in the warehouse, are in direct view of all people watching from the concession. As such, many reports are available of the historic events surrounding this battle.
Since the movie often switches back and forth between different events, it is important to know how all events fit in the overall battle. It is therefore that - before watching this movie - I highly recommend you first read the Wikipedia article titled "Defense of the Shihang Warehouse". In my opinion, reading this Wikipedia article will not spoil the movie, but instead provide the necessary background for watching this movie. Amongst others, it explains why the chinese soldiers were dressed the same as german WW2 soldiers.
Due to the movie not having a main character, you as a viewer will have an additional challenge of understanding what's going on. During some events I had the idea someone was put center stage, all but to find out that he is not seen for the next 15 minutes or so... I think it would have been very beneficial if the movie would have for instance a voice-over - e.g. Someone who was there - whom explained what was going on.
One big plus of this movie are the extremely detailed scenes. It is just a 'feast for your eyes'. If you for instance pause the movie, you often will be able to discover details (in the background) which you wouldn't have seen otherwise. Overall, the result is a very convincing portrayal of Shanghai during WW2.
In coming to a conclusion, I think we have here a movie that misses some necessary ingredients to make the viewer fully understand what is going on. The director and writers were probably so accustomed to the historic events, that they assumed that everyone else would also be as aware as they are... Why on earth they did not chose for having a main character is beyond me. As such, this movie is often a challenge to watch. Especially the first 15 minutes, I personally was left in limbo of what exactly I was watching. Giving it a second try after reading up on Wikipedia helped me enormously.
Taking everything into account - including the fact that this movie learnt me quite some new and interesting things about WW2 - I decided to score this movie with 7.3/10. Resulting in an IMDb score of 7 stars, I think this movie could have easily gained 1 (or even 2) additional stars if more effort was put in guiding the viewer better in understanding the overall situation. I recommend to first read the Wikipedia article "Defense of the Sihang Warehouse"
