Very Disappointed . We were very disappointed with this Bob the Builder dvd.  My children love Bob the Builder and own every video.  We were excited to hear that a new one was coming out soon (especially on Dvd).  However, it is not new!  Every episode on this dvd is on the other videos (or has been on the Nick Jr. show at least 6 months ago).  I would have never thought they would release a new dvd/video without any new episodes.  If this is your first Bob the Builder dvd/video, then I would recommend it.  If you own many others, then don't bother getting this one because you have already seen it
Output:
NEG
