There may be some things you do not know about Finney. He made mistakes in his theology, just as Calvin did, because he was only a man, but, unlike Calvin, he was used by God to win many souls, possibly more than any other single individual. Since most know very little about his history and influence, you may not know how his influence brought about great revivals in Korea and China which to this day are responsible for underground Christian churches in those countries.
If you have never read anything by the Goforths, Jonathan and Roslind, (lifelong missionaries to China, 1888-1938) you will find them immensley enjoyable, and a great blessing. However, do not look for any Calvinist teaching in them, though they were Presbytarians.

His ministry was in my area and he left little behind..they claimed salvation at the altar and then went away (thats what happens when Salvation is not all of God) ...Do not compare his theology to Calvin's, Finney's Theology was not Christian. He left a legacy of wood,hay and stubble..
