The idea that anyone could seek enjoyment from this is beyond me. I am fond of forgiving even the most embarrassing or bizarre sitcoms, because we British fundamentally try new things and aren't afraid of pushing the line- but Siblings is the opposite of this. It's packed full of cliches. Every episode is 100% predictable, whether that be because we've seen the 'character accidentally has sex with other character because of a lack of sobriety' trope a blinding amount of time, or because we know that the story will go like this: everything's good, something bad happens which forces the watcher to cringe in some vile attempt to achieve emotion, and everything gets better (or sometimes not- this is where the sole excitement stems from).
I appreciate that the show itself wants to do two things: advertise sibling relationships as positive and ultimate, and show the modern British millennial in a new, trendy sitcom. However, the sibling relationship is lacklustre. I would describe how hollow and psychopathic both Hannah and Dan seem, but these qualities are shown in the lack of chemistry between their characters and how the script seems adamant to disallow anything bordering on emotion between the two.
Their relationship exists purely to summarise the slapstick scene we've just witnesses for maximum comedic potential, which sometimes works for a minor laugh- I'll give it that- or to reference previous funny experiences that the two have supposedly shared. The actors are new, upcoming. I wish them well. But in this, whether it be the script or the tired material they must cover, I wasn't too impressed.
If Siblings represents the British millennials, we will be dead within weeks. The careless, 'up for anything' characteristic is fine to a certain extent to create a confident, likeable character, but when everybody is this, it makes it hard to appreciate anyone.
I shan't elaborate anymore, because the hope and eventuality of this sitcom is that it will be forgotten, and all I can say is that, if you're thinking of watching it, don't. Rewatch Fawlty Towers, One Foot in the Grave, or Peep Show for programs which utilise the painful moments of life to a successful attempt.
The music is alright. There's no obnoxious screaming, as far as I recall (I've watched the entire two series just so I can comprehensively condemn it). Apart from the swearing and occasional sex scene, it's safe to watch with family around. Perhaps you could tolerate in the background of something, like grating cheese.
