Hagee has some decent things to say...
However, it is vital for a Christian to follow Paul's injunction in 1Thess 5v21, 'Test all things; hold fast what is good...' The done thing today (by Christians) is to simply sit back and not bother with what is preached/teached from the pulpit/tv with the thought...'this person is a pastor/teacher and so they must know what they are talking about.' So often when I have listened to these persons I have found that they can be far off the mark and sometimes even preaching down right lies...
We must test/prove preachers/teachers, especially as the last seven years of this age (of Grace) approaches, Matt 7v15-23, 24v11,24, 2Thess 2v1-12, 1Tim 4v1-5, 2Tim 3v1-9, Rev 13v11-18...
