Answer:
is not the most important factor they consider when comparing two films
Step-by-step explanation:
The first option is wrong logically in that, while the charisma of the lead character is not the most important factor considered, it is definitely not stated as the least as other factors are also considered.
The second option is also wrong in that if the charisma of the lead character is the most important factor considered, more than 5 out of the 10 critics would have also voted Dracula as the greatest vampire movie ever made.
The last option is wrong in that if the charisma of the lead character is the most important factor considered, all 10 critics would have also voted Dracula as the greatest vampire movie ever made.
