As with season one, I have very few to little complaints with the actual episodes of the show (because it's awesome!). Actually, this season's DVD release fixed all of my main problems with the first season. The menus were easy to access and didn't take several seconds (that seem much longer than normal seconds) to load. Also, they have added scene selection! In conclusion, although this set doesn't have any bloopers or deleted scenes, the menus and disc content are wonderful. That's about it for those who only care about the quality of the discs, because the next paragraph is SPOILERS. Stop reading now if you don't want to know.
So, what happens in this season? Atlantis successfully stops the Wraith siege on the city in a rather amazing way (I'm not telling you how, you'll just have to see it yourself), but loses a valued team member in the process. Said regular does not die, but goes insane and runs away. Now it wouldn't make much sense to just leave a gaping hole in the middle of the cast now would it, so the writers invented a new character called Ronon Dex (Atlantis's version of a rogue Teal'c). Again, I will refrane from giving you too much detail on his character, you'll just have to buy, rent, or borrow the set (or even read the transcripts or check your library...). The mid-season cliff-hanger features the return of our lost insane friend whom I mentioned earlier. Of course, there are several more adventures before you get to the last three episodes. By the time you finish "Michael", you'll know that we can turn wraith into humans (and apparently vice versa in "Conversion"). In "Inferno", we get to see a sweet super-volcano eruption and see the Atlantis team get a new starship called the Orion. Finally, in "Allies" Michael returns and we learn that the wraith can feed on each other.
That's all for today's annoying review, I hope it helped (at least a little)!
