"This "historical account" has much of Eusebius's own theological agenda intertwined with the factual text including his view on God, Christ, the Scriptures, the Jews, the church, pagans, and heretics. At the very beginning of the volumes, Eusebius makes a statement about the divinity and pre-existence of Jesus Christ. This is a very strange way to begin a historical narrative proving that Eusebius was attempting to push his own ideas regarding the church into a text.[citation needed]"

http://en.wikipedia.org/wiki/Eusebius#Church_HistorySeems like someone isn't happy with Eusuebius' Church History, putting into quotes the veracity of the historical account and asserting an opinion.
But does that have any merit? I haven't read the work, but I've seen Orthodox laymen and priest alike cite this book as part of refutation piece for Protestant objections about the Early Church.
