None of what you said here actually happened in 13 Assassins. In fact, I sat and watched the big end battle scene again just to make sure. The 13 were fighting off soldiers from all sides. Soldiers weren't standing behind them doing nothing for even 2 seconds, what to speak of 5?
I'm 100% sure there was at least a few parts where a soldier was standing by just watching (really waiting to get killed) when he could of attacked, its a rookie mistake but I understand the samurai style they wanted to stress and I think they did it well, even though it was extremely repetitive.
You don't know that only one guy had a spear. There were over 200 soldiers present. The movie didn't introduce them one-by-one and break down what all they had in their arsenals for you. That would've been retarded. Also, you don't know all that happened along the way. Maybe that soldier found a spear lying around. It really doesn't matter. Does a soldier showing up with a spear fuck with the continuity for you or something? Or are you just nitpicking where there actually isn't anything to be nitpicked?
The thing about this was they made the scene look dramatic and deceptive, meaning they were implying that some treasonous shit just went down. It was the way the director captured that scene that sold me into thinking that, either way I honestly don't care and as far as nitpicking I'm not trying to nitpick but the film really sucked that bad. I'm sorry but it was fucking horrible and it felt like a knockoff of this film:
even down to the approach:
-The first 30+ minutes was spent when the leader was coaxing and recruting assassins/bodyguards to aid in his impossible and greatly outnumbered fight against the emperor. There was also A TON of politics involved that caused this entire conflict and it was shown as soon as the movie started.
-The last bit of the film was a huge major fight that was almost an hour long as soon as the leader arrives, assassins begin by launching arrows from the rooftops which kills a large majority of people and most of the paths are blocked off by ambushes and traps. Everyone starts dying one by one untill there is only one person left standing (possibly 2 can't remember atm).
Now flip the movie, In 13 assassins there was a part where a mayor? blocked off a path so the emperor could not go through. In B&A there was a part where the policeman of the city blocked off the path from the assassins and aided the bodyguards to escape through it. When you put these 2 films side by side they are completely identical even the assassins have control of the town while the bodyguards try to protect their leader as they travel through it.
I actually haven't seen B&A in over a year but I can recall it better than 13 Assassins because it was more memorable even though it was a bad film, if that tells you how much I thought 13 Assassins sucked. I'm sure there are more similarities but I would have to see both films again but I have never seen 2 unique films share the same exact approach and practically storyline.
