There are two ways to look at this installment of the Blue Collar Comedy Tour:
1. If this is the first time you have become acquainted with the gang, this will likely be a 5-star experience. The bits are still funny, and the "old pictures" segment to close out the show is almost worth the price alone.
2. However, if you have already viewed parts one and two in the series, then (for likely the first time) the material will begin to really feel stale. "Rides Again" began the over-exposure, while this one only continues the process. Without that great last segment, the entire show would have really felt musty.
In terms of evaluating each individual comedian:
Bill Engvall: A bright spot; really engaging stories that may be his best performance of the three.
Ron White: A step back from "Rides Again"; loses some of that biting wit/sarcasm that is his hallmark.
Jeff Foxworthy: Spends WAY too much time on one rather uninteresting subject, and routine suffers as a result.
Larry the Cable Guy: Same old, same old here as even big-draw Larry starts to get a bit derivative and sinks into out-and-out crudity a bit too much.
Thus, your opinion of this third (and last) entry into the Blue Collar film series will likely be determined by your previous forays into the series. By and large, the jokes are still funny, but their freshness is what is seriously called into question.
