Season 4 of Man vs. Wild contains some of the best episodes Bear has ever put together, however, I was disappointed in the actual DVD package it came it. The front of the case was pretty cool, sporting a holographic Bear sticking out. However, the entire case is made of cardboard, and a small cardboard insert containing the DVD's slides out for access. It's really flimsy, in fact, while I was carrying the case, the insert slipped out, and the discs fell on the floor, luckily with no damage.
My suggestion: keep the outer DVD case in which the insert is contained, and toss the silly, unprotective insert. Go to your closest electronics store, and purchase 3 of those super slim cases and store the discs in there, and then store the slim cases in the actual case. This way, your discs will be protected.
Otherwise, the show itself is fantastic, one of the best seasons yet.
