I have always had a theory that "Someone like you" feels like Wilson's good bye love song to Yuna while paying tribute to their working history/friendship over the years on the assumption Yuna will retire soon, and that would be the end of their competitive days. It is full of forlorn feelings that is intimate, familiar, complex and as intense as lovers goodbyes. His choreography for that program feels like a collage of many of his 'best of' moves to celebrate and paying tribute to their collaborative days. Many moves subsequently came to be known as Wilson-esque signatures that became the de facto choreography vocabulary of the COP era. In that respect, it may feel generic by today's standards due to its familiarity, but they are also what established Wilson's brand. Their contribution towards each other's success cannot be understated. Yuna's sporting and artistic success validates Wilson's COP work, and also vice versa.
Bear in mind, 'generic' moves doesn't always start as 'generic' until someone first establish them. Others follow them. Or them being replicated due to established success. There's a fine line between something described as generic when it is an 'imitation' vs something that is 'classic' when it is being performed by the original team that founded them. Otherwise it is like going to a Prada shop and complain why everything black and boring. Or go to a James Cameron movie and complain there's too much special effects and why the love stories always so cheesy?
I'd argue the middle section 'on my own' does contains certain archetype Wilson/Yuna choreography, but actually it fit the messages of the music well. 'On my Own' is Eponine's internal dialogue about feelings and contemplation about love, hope, loss, regrets, lingers of sweet bitterness; to learn the meaning/value of true love and acceptance of selflessness. The choreography therefore should be without pretension or fuss and at its most intimate natural state; heartfelt and honest. Choreographically, to harness that visceral fortitude Wilson became familiar with Yuna over their years together, he naturally select their classic moves which embodies these biographical qualities that fit the story the best, something he tends to do with his skaters. Perhaps this is why that part reminded programs like "Someone like you" which shares similar biographical qualities. This is not to say the work could not be more original or creative, but it does explain why such an approach has been adapted rather than blame it entirely on complacency.
