I am not overly suprised that this happened. After all, it assumed that everyone spoke or could understand English, but they could not.
I think it would be better if there was the option for other languages, like French, German, Spanish, etc. In addition, films and comedies, etc., should also be in those and other languages and not merely in English, while featuring the best comedies of those other countries.
I should think that IFE in pure English and featuring American films and comedies would be very well suited to an airline like Southwest. There would be very few language problems and everyone would know the comedies.
