There are obviously a few faults to Log Horizon. The reason I voted this that high is a) it deserves more love and should go up in the anime list and b) is leagues better, in my opinion, than some of the stuff coming out these days. The main glaring fault in it is that many of the characters seem perfectly at ease in their new environment, the former MMO 'Elder Tale', now their world. No one panicked, there was no mass hysteria or anything, and frankly, this was done much better in SAO's episode one. However, it is becomes apparent that they haven't forgotten their situation but have attempted to adjust.
The first few episodes of Log Horizon are there to establish a setting. It starts out slow, which unfortunately lost a few watchers, explaining basic MMO concepts and features, introducing the main cast and so on. Around episode 5 it picks up, having finished a sort of prologue and begins the main story. If you hang around until then, you won't be disappointed.
There are several plot twists that were actually fun to watch, of which I only managed to guess two. Log Horizon also focuses on the premise of 'politics'. If you think about it, it is obviously pretty important, given that the several thousand in Elder Tale have no overarching law governing them. Anarchy is obviously an effect, and this is what the protagonist attempts to solve. This was actually pretty refreshing from the recurring theme of violence solves everything that seems to come up in Anime. It may sometimes get slow, but if you bear with it you won't be disappointed!
Art wise, there is certainly quite a bit more left to desire. While Log Horizon's art is in no way bad, in fact it is very well done, it is not very good either, going more on mediocre. It does not really affect your enjoyment of the show. Several special effects were done pretty well, especially skills of the players, but other than that there wasn't any real eye candy.
Sound, I felt, was pretty good. Unfortunately I only really pay attention to the OP and ED, and in this case both were nice. The OP had several English lyrics, and the tune in general was nice. I tended to skip the ED though. The OSTs were all good, but the fact that none really come to mind show that it isn't anything extremely amazing.
Characterization is one of the strong points. Shiroe's development isn't explicitly shown, but his slow growth from introvert to leader is done very well. Several side characters are also done pretty well, but some were neglected, like Naotsugu and Nyanta (btw this guy is weird... Nyanta that is. Idk why). And the romance in this has left much to be desired; in that the little that is there isn't done very well, especially who likes who. I felt that it didn't really fit with the series, they should have gotten most of it off.
Log Horizon is one of the better series to air recently. While it certainly does lack in some areas, it overall more than makes up for it. Consider watching it, chances are, you'll be pleasantly surprised.
