At one point, the text at the top started saying "Rate NaN movies".
You seem to start off with extremely popular movies. Those movies seem unlikely to generate a range of ratings. You might consider starting off with movies that a large number of people have rated but which polarize people, which would help differentiate people sooner and improve the quality of the circles.
At one point the "I didn't see this movie" links became french: "Je n'ai pas vu ce film".
In one category, I hit "I didn't see this movie", and later the same movie showed up in another category.
I found it slightly odd that the rating scale goes from 0.5 to 5 stars, rather than 0 to 5 stars.
I rated all the films deegr showed in the first batch, and they all disappeared, but now I don't see an obvious next step. The rotating deegr explanation banners at the top mention something about "refine your search after rating a few movies", and shows an icon for that, but I don't see that icon anywhere in the interface. I finally found that clicking on the "Deegr Circle" dropdown, then "Deegr Circle" under that, led me to something useful.
Once I get to the mode showing a circle of other people, I don't see any options for "I haven't seen this film" anymore.
Once you start recommending a circle of people, and recommending other films liked in that circle, that encourages rating those films too, which seems unlikely to change the circle.
I'd love to see an explanation of the name. Best guess: modified form of "dig"?
