Hangul is great, but don't try to use it for English. Try writing "Larry really loves the zoo very much". You get "Raeri ri-a-ri reo-beu-seu da joo bae-ri meo-chi".
In other words, you lose the L/R and V/B differences, and words like "much" can't end on consonants, so you get "Muchi".
Hangul has no sounds corresponding to "V, F, R-L, Th, and 'woo'".
