“There were a few awkward sentences but on the whole the book is very well written.”

“On the whole” is used to make a generalization about something. When you look at just the parts, some parts are good and some are bad. When you look at the whole thing, you can see if it is good or bad taken as a whole.

「待ち時間は長かったけど、子供たちはとても喜んだ。全体的にテーマパークはとても楽しかった。」
「微妙な文は少しありましたが全体的によく書かれた本です。」

「On the whole」は何かを全体的に言うフレーズです。部分を観れば、良い部分と悪い部分があります。全体を見ると、全体的に良いものか悪いものかがわかります。
