And now I can finally say:
I had a review that took two weeks and a review that took two years.
In December 2021 we submitted a paper to PRL and while one reviewer loved it, the other didn't like it. Sadly there was not much hope to win against the comment, "I don't see why I should be very excited about this result ... which is needed in my eyes for a publication in PRL".
After admitting defeat, we send it to Phys Rev Fluids and I'm super happy that Prof. Howard Stone accepted it right away without sending it to further reviewers.
In the paper we discuss the dewetting instability of a thin liquid film on a switchable substrate. We actually found a cool metastable rivulet state.
