The site itself is in russian, but search queries in English work perfectly.
Content from English speaking countries almost always (literally around ~99.9% of the time) includes the original English audio track. You will have to manually set language priority in your video client as russian audio is set as the default track, but this should be easy to do.
Keep in mind that non-English movies/series will include the original audio and a russian dub/VO, English dub/VO will not be included. English subs are typically provided for non-English content.
Some B-movie are actually pretty good have interesting concepts. Even the bad ones can have redeeming quality (80s aesthetic).
The clips in the article are about as generic as you can get.
