I don't disagree, the first two seasons were very much "number of the week" episodes. Season 3 ramps up the plotline quite a bit, wrapping up the big HR story arc early in the season and introducing the new bad guy, Samaritan. Who is an opposing super-AI, btw. The rest of S3 is the team fighting to keep Samaritan from going online, and S4 has the team trying to keep under the radar as the two AIs start battling. It's definitely grown into a more story-arc driven show, and the Numbers have become more often than not relevant to the ongoing plot.
