Note: The reviewer thinks the original game is still great.
The reason for this low review is because he thinks the enhancements are lackluster, have ben available trough mods for a long time, has new bugs and the novel-style cinematics aren't good, plus some performance issues (believe it or not).
I think it's a fair score, and it's more about preference than anything els. From what i've seen, i think the new cinematics are much better than the old ones. It's barely ben released, and wen the patches and the community mods come out over time, it'll be much better than the modded version.
