An uninspired movie filled with computer generated images (CGI), that is merely an okay watch!
After Sony loaned Spider-Man - its crown jewel comic book property - to Disney, it had to settle for side-characters from that universe. Venom, a member of Spider-Man's rogue gallery, is not a standalone character in my opinion, but Sony gambled on Tom Hardy, and the box office data shows that they won (with over $850 million gross worldwide as of the writing of this review)!
The movie revolves around the alien Symbiote (the black goo that gives a human host super powers) family that want to take over the earth. As the trailers show, there are a few Symbiotes in play, and that makes the movie a little too heavy on CGI.
I have never been a fan of Tom Hardy, but I have two positive things to say about his performance in Venom: i) I got to understand him in this movie without the need for subtitles, cause his mouth wasn't covered (see Bane in Dark Knight Rises, Mad Max in Fury Road, and his character in Dunkirk), and he was speaking with a North American accent, and ii) he was unintentionally funny. I say unintentionally, because I think Hardy, as a supposed character actor, wanted to show the internal struggle between his character (Eddie Brock) and Venom (the Symbiote), and he was constantly fighting with himself.
Bottom line, it's a somewhat humorous movie and an easy watch for a Sunday afternoon. I'd give it a 5.5/10.
