I just picked up Season 4 and the case is a let down! Its not textured like the others and its just a fat case in stead of the card board fold out! But it is only $30!
Indeed, the packaging was a big let down for me as well. I'm kind of picky about things like that, so I'm looking into selling my individual sets and picking up the newly released four season box set.
Even an option to purchase a new case which matches the other's would have a welcome option for me. They did that with Season Six of The Simpsons. They unexpectedly switch the package design to a flimsly plastic head and when there was an uproar of backlash over it from people who had previous sets, they gave an option to buy a new box which more closely matched the previous design. Every subsequent box set of The Simpsons has had two differnt packaging options (traditional & character head).
I'm stoked for people who passed on the HIT box set and waited for the Final Season as an individual release, but it seems to me Lionsgate defintely should have went with the same packaging style as the others. At least with the initial batch. Afer all, it was only one box set. Maybe if they had a bunch of seasons left to release a packaging change would have made sense, but with only one?
*sigh* I guess nothing in life can be perfect.
