The start of House of the Dragon reminded me that I started to watch Game of Thrones twice before I properly watched and loved it.
Both times I gave up because I found it dull (in truth I couldn't tell the difference between all the Stark-ish boys). In the 3rd viewing I resolved to make a note of their names and relationships to be able to follow the story. I went on to love it.
Similar story with Lucifer. I watched the first episode, thought it was cheesy old crap and stopped. I then gave it another go some months later and revelled in how cheesy it was - loved it.
It makes me wonder what other gems I might have tried and failed to appreciate.
What series did you have to give a few 'goes' before it clicked?
