A 6 for me. As my 6 and 10 year old children pointed out, "They mispronounced 'symbiotes' ".
Also, there is no Spider-Man, and nothing in it screams "VENOM" to me...
...except where we get to FINALLY hear him say "WE ARE VENOM". Which is why I still rate it better than a 5. Got me pumped seeing the last 10 seconds.
