In terms of role positioning, the town sheriff played by Schwarzenegger must be a traditional hero who is extremely loyal to responsibility, and has a strong sense of justice and appeal. Therefore, when facing a mercenary squad, he will never Choosing to let it pass with one eye closed; facing the big drug lords who offered tens of millions of dollars in "road money", he took out the handcuffs dismissively. This unhesitating courage and determination also urged his police officers to stand with him courageously, to give up their lives and fight with all their strength. Secondly, in terms of action style, the momentum and popularity of the "big gun" is indispensable. The shotgun is already a standard weapon of Schwarzenegger, and it seems invincible to shoot while advancing. Again, although the hand-to-hand scenes must be less than ever when you are older, the only one in the film who threw the enemy gunner directly from the upstairs to the downstairs is impressive, but at least the tough guy temperament that can't be beaten is still there. At the end of the film, he was stabbed in the thigh by the drug lord with a knife, as if feeling no pain, he immediately pulled out and thrust it into the thigh of the drug lord, causing the drug lord to completely give up resistance. However, the audience can also clearly feel from the action scenes in the film that Schwarzenegger is already a bit unable to move, his movements are obviously slow, his spirits are also slightly sluggish, and the heroic aura is far less powerful than that of the past. The film also tries not to focus too much on Schwarzenegger alone, but uses other roles to attract young audiences. The two young police officers under Schwarzenegger are cool brothers and beauties, adding love scene elements to the film. The weapon fan freak is a commonly used geek funny supporting role in Hollywood, and his off-line actions in the film can make some laughter. The big drug lord himself is also a glamorous sportsman, and the sportsman driving a cool car is a major attraction. The end of the small town blockade is not Schwarzenegger’s traditional action of "one man is the gate, but no one is the best", but a collective battle of "one hero and three gangs", and several police officers under Schwarzenegger. They all play their respective roles in battle. As for the ultimate hand-to-hand fight between Schwarzenegger and the big drug lord on the border, the big drug lord will also use the lock technique in the more popular free fight to develop the skill versus power PK with Schwarzenegger, so as to make the figure bulkier. The big drug lord, far inferior to Schwarzenegger, possesses the strength and attraction to fight Schwarzenegger. Compared with the "Red Police Veyron", which only focuses on Stallone and has a very traditional style, "Back to the Water" maintains the iconic elements of Schwarzenegger's movies while incorporating a wealth of features that cater to the trend of action movies, thus showing Good entertainment quality.
