Time Team

[Epictetus]

One of my favourite television shows is Time Team, where they find a place of interest and quickly excavate it. Many times they also have a bit of reenacting or living history to illustrate something-or-other relative to what they are excavating.

Here's my question: I have never watched or participated in any real archaeological dig, and I've always wondered how real professionals view the show. The time issue always bugged me a bit, because they do the dig so fast I wonder if corners are cut. So for those of you who are real archaeologists, or who have participated in real digs,what do you think of the show?
