An origin story for an iconic character such as Venom easily aroused major interest in the comic book adaptation furor of the modern age. However, that furor should've dissolved by the announcement of its creative team rather than a trailer or PG-13 rating. The director & writers of Venom are responsible for Gangster Squad, The 5th Wave, The Amazing Spider-Man 2, The Dark Tower and Fifty Shades of Grey. If you think that combination would produce another The Dark Knight (2008), The Avengers (2012) or Logan (2017), you were self-deluded (or not paying attention).
Venom should've been an unmitigated disaster. However, if one is able to discard all expectation or notion of what a Venom adaptation should be, you might be able to get sucked into the entertainingly vacuous spectacle of it all, which was replete with humor and unapologetic bombast that even at its height feels more measured and considered than the third act of any recent D.C. Extended Universe film where everything descends into people throwing large objects at each other.
Venom is not a great film, but its also quite harmless. It sought to be entertaining rather than thoughtful, and achieved that very result. It may be a disappointment to fans wanting a faithful adaptation but as I said before, that expectation should've been dropped upon learning who the director and screenwriters were.
