Is Splice weird as hell? Sure. Is there two human-on-alien sex scenes? Absolutely. Is one of those scenes a rape scene? Uh huh. But is it still somehow a genuinely good movie? Yup.
The integrity of your podcast would be compromised if you sincerely asked "How did Splice get made?".
But, on the other hand...alien rape. So, yea, I understand your struggle.
