Strong on enthusiasm for the things of the Spirit, weak in a clear theology and ecclesiology on how it all works.
Unleashed is really the personal testimony of Gavin and Ann Calver's experience and their desire to see the traditional denominational church released in ministry, miracles and evangelism, as described in the NT book of Acts.
However, the book is weak on any clear strategy on how such a NT church model can be established, vague on any practical ideas on pastoral leadership, and totally lacking on any theological understanding on ecclesiology in a post modernist age.
However, such glearing omissions, can be forgiven for their obvious enthusiasm in wanting to be used by God to find a new expression of church in the 21st century.
