The movie is about a symbiote (an alien life form combines itself with other hosts) that named Venom who becomes one with a reporter Eddie Brock. The casting of the movie with Tom Hardey as Eddie Brock/Venom was a good choice. The plot on the other hand was terrible. The plot in no way followed the comics whatsoever and ruined the character’s unique self and origin.

At the beginning, Venom did not come to earth on a space ship. He came on a meteor. And he did not get experimented on by the Life Foundation right away. He latched on to Peter Parker/ Spider-Man until he took off the suit forcefully and then it latched on to Eddie Brock, and the fact that Venom’s appearance had no spider emblem or did not even use the symbiotes webs at all.
Now I know if you make a Venom movie without Spider-Man it’s going to be different, but it does not excuse the fact that they had to change the whole plot.

The villain in the movie was Riot. In the comics, Riot in fact is Venom’s cousin and is good friends with him. The movie lacked an excitement because there were not many action scenes. It was mostly dialogue and drama. It was in the end of the movie when Venom had fight scenes and action. The rest was a lot of talking.

The one big rule that was broken was the rule of WE. When a symbiote and a host become one they only refer themselves as we at all costs. However, Sony Inc. did try their best on a movie of a beloved character, even if the movie was terrible.
