I have never watched Epix, so I cannot comment on it, but Reelz is absolutely worthless as a movie channel. Perhaps Reelz has some other redeeming quality, but I only notice it when they are showing a movie that I would like to watch. I tried to watch Hoosiers last week and was extremely disappointed. I could accept the fact that it was SD, but I could not take cutting of entire scenes or the fact that it was pan and scan.
Hoosiers might have been an exception, but if that is the way Reelz treats movies, then I will not watch a movie on Reelz, even if it is in HD. A channel that is dedicated to movies should show the movies uncut and in the original aspect ratio. Otherwise, the channel is not worth the bandwidth to have in HD.
Reelz has some original programming that I would like to watch but the SD on that channel is among the worst of D*'s SD. It even looks bad on a small 24" set I have.
As to the movies, meh. Reelz is no worse than lots of other channels we have now that have ads and cut the films, so I don't see that as a big deal.
Epix has Lionsgate and a few other studio's films that show up nowhere else uncut.
