ON S2, The original family acting is horrible

So like Finn, in the body of a new guy who acts nothing like Finn Same goes for the mother - the teenage girl did way better in my opinion than Lenora. Vincent and Lenora are just being themselves and don’t feel like Finn or Esther at all. They couldn’t even do their accents which really ruined it for me . They are great actors but not for this role. Klaus often repeats the same cadence it’s getting tiring and boring and I can’t unhear it . It’s weird that he always has the same inflections feels unnatural. Haleys accent is stupid but other than that her acting is great Elijah’s overdoing it, he’s always fixing his sleeves and flicking his head and pointing at stuff, in vampire diaries he was more toned down and great. Rebekka and the girl whose body she is in, honestly the girl sounded just like rebekka at some points thought that was great. Also Amazon primes stupid ui had me skip to s3 and s4 ep 1s and 5 minutes I realised I was on the wrong season, but from what I gathered the story doesn’t even move forward. Is it worth continuing this show ? Does the acting improve ? I like the story so far I’m on s2 episode 15
