I am actually quite unsure of why so many people don't like this movie. I found that Venom was actually quite enjoyable and when I realized that I still had an hour to go I was thrilled. I think my appreciation for the movie comes from the fact that I'm not interested in the comics and therefore have nothing to compare it to or expectations as to what should happen in the film.
There is a surprising amount of 'brutal' scenes, but I think it actually made the movie quite genuine, not to mention give more personality to the Venom and shows the progression of the character as he has a change of heart and at the end.
I loved the portrayal of Eddie and Venom. Though I do believe that it was supposed to be R-rated? Featuring more blood and gore and I am so glad that it wasn't so.
The only thing that disappointed me was the fact that I waited so long to watch this movie. It was brilliant and I am so pumped for the second and hopefully the third.
