That's just more superficial reasons. Some of the worst CBMs have had stuff like that. For example, Ghost Rider had horror elements, Johnny Blaze had an inner conflict etc. Didn't help the movie.
The fact Brock is a reporter doesn't mean diddly squat, IMO. If we are talking faithfulness to the characterization, then they have thrown that right out the window. What about the fact they have totally ignored the whole foundation of the character - the fact he becomes Venom because of his hatred for Spider-Man? That the symbiote was Spider-Man's which he rejected before it went to Brock etc? Sony has just taken a dump on the whole Venom mythos there, much like they did with the Goblin one in TASM 2. But then this is Sony. Who is really surprised by that.
I still see nothing here to be impressed with. Not as a movie, or if I was a Venom fan. I'm baffled how some people think this is the perfect depiction of Venom.
