Can Brits actually understand them pretty well?

I've never understood why people dislike subtitles. I always turn them on even if I'm watching an American movie. I like to catch every bit of dialogue and not miss anything. I know people who HATE subtitles, but if they miss what someone said, they will go back and rewind it to hear it again. They do this 5-10 times during a movie, and it's really annoying. It could've been easily solved by just turning the subtitles on.

Americans can barely understand each other and that's it. They are ignorant of most of the rest of the world.

I am from germany, so english isn´t even my first language.
Anyway i can understand them well.
Maybe yanks are too uneducated and should widen their horizon instead of watching the kardashians rerun again.

Is it really that difficult to understand accents across the pond? I am a non-native English speaker and have a foreign accent, but I have been told that my North American pronunciation is otherwise very good. I am quite unused to British English and didn't think that I had much problem understanding this movie without subtitles.

I don't understand why this is an issue for people. I'm Canadian and didn't have trouble at all. When it comes to the cockney rhyming slang, it's easy to figure it out when it's put in a sentence.

It's not really an issue with the accent, but rather getting familiar with the slang. It's the slang that throws people off. If you hear words you've never heard before it just sounds like gibberish, but once you understand the slang the comprehension is not much of an obstacle at that point.

My main issue with Brit talk isn't the accent, but the predilection for mumbling and slurring. It all becomes something of a rumble.
