I had a lot of fun with the remake, especially the cutscenes were awesome to look at, but they kind of messed up the story a bit and much of the level design was broken.
But yeah, Bleemcast is not worth getting. It is a neat gimmick, but not a real thing you should bother with. There is a special effect you can use on the PlayStation 2 that makes original PlayStation games look smoother, so that might be worth checking out too I guess.
