The third film had no correlation with Venom's saga.
That's rubbish
both mediums showed the following
symbiote coming to earth from outer space
symbiote sneaking into peter's apartment undetected
symbiote bonding with parker during a tragic dream sequence
parker awaking in the middle of the city upside down in a suit he's never seen before
pete testing out new abilities and enjoying it
pete becoming darker
pete taking symbiote to connors and him analysing it
eddie brock taking pictures of spiderman
eddie providing jjj with wrong information
eddie getting fired
parker in a suit being very confident
parker's realisation that the suit is affecting him negatively
spidey taking it too far with his villain confrontations and wanting to kill them
parkers getting the suit off at the church
eddie gaining the symbiote at a church
parker and eddie fighting with venom telling pete he's realised his identity
eddie telling parker his motivations
inevitable parker realising that sound is a weakness and using it to defeat venom at the end
if that is no correlation in your eyes, then I seriously don't know what is...
it's practically the same story.
