Sorry if this wasn't clear. After clicking a poster and the tick appear, click the green "Next" button to see posters like the ones you have clicked in the first place.

I assumed Next just showed another page of results. Maybe you should popup the next button only after the user has clicked on a poster? Also, after I clicked next, I got what appeared to be unrelated posters which is what made me think I was looking another page of random results.

Thanks for your feedback and your suggestion. Findmelike obviously didn't work so well in this case - we should be able to offer more accurate recommendations by refining our model based on the data we have obtained today. Also, we clearly have some UX work to do. Our mobile experience is not very convincing.
