As visible in the discover documentation, we don't have a vote_average.lt parameter, but a vote_average.lte parameter.

oops, thank you. but now i see a problem, if i do the same but now with lte, the firs result is not below 2 as you can see

this is the URL now:

"https://api.themoviedb.org/3/discover/movie?api_key=YOUR_API_KEY&vote_average.lte=2"

this is the first result
