I like Star Trek Strange New worlds - which I know not all trek fans do.
I even liked what they did with James T Kirk in last night's episode - he was still very smart adaptable needed to be in charge - and was teased about that - charismatic but a bluff he pulled without enough information got him killed - it was fine as it was alternative timeline situation. He wasn't suddenly and inexplicable stupid - it was a recognisable version of his established character.
But you didn't find the singing crab, the talking seagull, the shapeshifting witch, or the fact that they were half-girls, half-fish 'odd'?
All that was not odd at all...Just the fact that the actresses playing them were of different ethnicities?
I read a time traveling witch story - ( I read classic as well) clearly suspending a lot of disbelief but what pulled me out the story was 10 th century Scottish kitchen peeling potatoes - just no.
I had a similar irritation with London based working class repair man who discovers magical society and rapidly gets involved - all fine talking book/animals world wide conspiracies - jarring bit was constant talk of him attending public school - when it became very clear they actually meant a rough state comprehensive.
My kids were much more Pixar golden age and Studio Ghibli films so Little mermaid isn't something I've personally watched and not keen on live remakes so haven't seen latest versions - so I can't say it's something I personally would notice or not but It can be odd details that jar even when rest is clearly fantasy.
