After watching the first 4 seasons it became obvious they had to make a few changes in order to keep people interested. In series 4 they added more guest appearances to try and keep things fresh, but it lacked the quality of the previous 3 series. So, the idea of the capture of the a team with the added thrill that they were to face a murder trial, not just for robbing the bank made it that little bit more serious, as the death penalty was the sentance. The first 3 episodes, in my opinion were perhaps some of the best ever aired. Infact, the cliffhanger at the end of episode 2 left me at the edge of my seat. But after those first 3 wonderful episodes, the series really became poor, one episode especially called 'the crystal skull'. Which to my mind was the worst a team episode ever made. I would describe it as being a joke! There were some good episodes like 'The Say Uncle Affair' and 'Point Of No Return' and even the episode 'Without Reservations' had its moments. But the rest was poor. Only 13 episodes and no complete ending or pardon for the a team makes it seem like a series cancelled because of how poorly it was put together.
Its probably obvious that the show would have come to end after this series regardless of how good it could have been, it had its time. But to me its such a shame that after the first 3 great episodes it just went downhill, with new real quality or effort. If you are a new fan and really enjoyed the first four seasons and are thinking about getting this one, please dont expect much - Great in parts, horrible in others, dark, depressing and quite boring. Watch the first three episodes, treasure them and then throw the rest of the set away.
