Rambo 4 is actually worth watching (Ive heard it was too violent for a theatrical release)
The other thing that annoys me is when film companies rename the original film - I believe First Blood (pre original Rambo) is now "Rambo 1" and theatrical release of Rambo: First Blood pt 2 is now Rambo 2
I believe this is the case anyway
Rambo 4 is most definitely worth watching

Made me laugh out loud, almost like comic/comedy levels of gore, all crystal clear on bluray.
I wanted to import it from the States, not only as it's not even out here yet, but because I wanted a non-BBFC edited version.
I always get narked when I pay for a movie, and they've hacked bits out, even as stupid as the original Matrix movie. I got the R1 copy at the time, and later learned that the R2 copy had something like 40 secs edited out, all the headbutts! Why?
Yes, the renaming is a bit pointless too.
In fact, my Rambo 4 disk is just called "Rambo" but I called it Rambo 4 in here, or people would probably think I meant Rambo (First Blood Part 2).
I also got First Blood on bluray, as the import price is only £9 new.
Looks good too. Not as good as a brand new film release, a few of the scenes looked artificially sharpened, to the level they had the mosquito effect, and looked almost out of focus. For the most part though, it looked great, better than I'd expected, and all those panoramic shots of up the mountain, in the trees, look great.
Vin.
EDIT: As far as too violent for theatrical release, I don't think so. I watched the special features, and they said that they sent it off for certification, as is, expecting it to get an 18, then they'd trim it back a bit to get an R. They said they were surprised when it came back with an R rating as is, so nothing was cut. They said there'd be no Unrated version, or Director's cut, as everything they wanted to include, is all there.
