After a bit of thought I prefer the new family.
I never played the Goths in Sims 4 because they just didn't feel or look like the Goths. This version is better imo.
Initially I thought Bella looked older, but she does resemble her past self, the original Bella always had a darker skintone.
Mortimer is great.
Not sure about Cassandra. She's much softer looking and less edgy than previous sims, she needs some work.
But Alexander. Poor lad. To be fair the aged up Sims 2 Alexander had an unfortunate face. Maybe that's what they were going for.
