This is the cream of the crop... in terms of miserable moviemaking, that is. Nevertheless, don't think you're in for some Uwe Boll stuff, the two don't share the same career at all.
In fact, Plan 9 offers plenty of laughs, inept acting, mistakes, flubs and the entire dictionary of what not to do in pictures. There's no story (well, there IS one, but it's quite atrociously written), the actors (forgive me for using that word) deliver their lines with the conviction of an ice pick and the effects are anything but special.
Watching it at a party or with a group of people insures almost immediately laughter and watching one of the worst films of all time.
The restoration isn't the best there is out there, but it's the best the film ever looked so far. For the price, it's a keeper.
Also, stick to your former DVD with the same cover since some special features are absent from the present edition. Nevertheless, it's great fun, and if you like commentaries, Mike Nelson's is just a load of fun, improvising as he watches, making funny voices and giving us plenty of reasons to enjoy the investment.
