Translation:There is nothing interesting at the cinema.
The Hebrew indeed has ב which might make you think "in the cinema" but as EDI788785 points out, in English, at least, you'd think someone was describing something about the inside of the building. I think DL meant, "There's nothing interesting at the movies." No good films are being shown. BTW, hats off to 4kzaj for a 900-day streak! I thought I was dedicated. My 390 would have been about 600 but for a trip to Israel and a 3-day Jewish holiday (Rosh Hashanah+ Shabbat) , and my friends think I'm obsessed.
