Monday Night Wars - Under Shows/Originals. Gives a pretty good overview of the NWO and Attitude era throughout the 90s.
NXT Specials - Under Shows/In-Ring. Arrival (2/27), Takeover (5/29), and Takeover Fatal 4-Way (9/11) should give you a good sampling of some of the best of what NXT has to offer. This might be the developmental league, but a lot of people (myself included) feel like this delivers a better and more consistent product on a weekly basis than the main roster.
