For a very brief period you probably could have said that the Anglicans were basically Catholics with no pope. I don't think you could say that by any stretch today. You could probably say that there are SOME Episcopalians that are a lot like Catholics, but the heirarchy in their church is doing a remarkably good job of driving them out and fully into the Catholic Church.

The Episcopal Church is a small-c catholic church, and is part of the Anglican Communion (the worldwide outgrowth ot the Church of England). The two churches are similar in many ways, but dissimilar in about as many ways. Anglicans are not quite reformed, but neither are they as hierarchical as the Roman Catholics.
For a quick overview of the basic beliefs of Anglicanism, peruse the Thirty-Nine Articles of Religion.
It's a little more complex than that. I've heard them (Anglicans) describe themselves as a third way between Protestants and Roman Catholics. There is a Protestant(conservative evangelical) wing and a wing that is very close to Rome. The Church in England which is under Government control and the American (Episcopalian) Church is dominated by heretics(often referred to as theological liberals.) I guess they are a third wing.
Seriously, they consider themselves Catholics of the Anglican Communion ( on a good day ); and MOST reject Spong as a heretic.
