In english ? I never noticed that the english version of FF7 was bad, but it might come because I'm not a native.
However in french it's definitely terrible, as it is based on the english one (instead of directly japanese), and contains some mistakes, too literally translated sutff, and some leftover text in english. Many things are abbreviated too much to fit on the screen. However it did never prevent me to enjoy the game despite being poorly translated.
Also, we saw on the FF4 article that "retranslations" are not always that good. The FF4 retranslation is purposely doing everything the reverse way of the original, and they added swearing where it was not present, as well as making random stuff up.
