You're right French have everything dubbed in french, also English teachers are very bad, which doesn't help, I would say that most French kind of understand basic written English, but when spoken, it is so different than anything they heard that they are not able to translate sounds to the written words they might know. French has a lot of words which are close or exactly the same as English, but doesn't sound the same or mean completely different things, which doesn't help. (example: 'argument' in English as in 'having an argument' and 'argument' in French as in 'ton argument ne mène nulle part' don't mean the same at all, other words can mean the same such as 'agile' but sounds like two different words when pronounced in French vs English) And then you have pride (the wrong kind) coupled with the fear of sounding ridiculous, which is why 99% of French you hear speaking English has a very strong accent, they're not trying.
