To say that 'Agents of S.H.I.E.L.D.' is intent on making sure its second season sticks firmly in the minds of viewers is an understatement. Something to examine with the new show is that Coulson and S.H.I.E.L.D. have to contend with two forms of opposition, that of HYDRA and that of Glenn Talbot and his obsession with bringing the reformed and fledgling S.H.I.E.L.D. to book.
In the comics Talbot (created by Stan Lee and Jack Kirby) was just as obsessed with catching the Hulk as General "Thunderbolt" Ross. While he is not cast in the light of straight up villain, he is here to stay as both an opponent for Coulson and his team, and as a foil. And he really scratches that classic Marvel Comics itch.
As far as villains go, we are not short of them. In addition to the Absorbing Man, there is also HYDRA superior Daniel Whitehall's right man Bakshi, who is determined to keep the team from maintaining world order.
One thing to note, is the continued hinting at the Kree (major Marvel alien race) and their involvement in the Earth's affairs. The writing that appears upon the Obelisk from episode 1 is clearly Kree. This, and the Kree corpse from Season 1, and any mysteries surrounding Skye and Coulson's 'abilities' brings up the possibility that they will become versions of the Inhumans within the confines of the Marvel M-verse.
Despite the dearth of villains that appeared in this episode, I enjoyed it immensely. There was a healthy balance of good writing with fast pacing, so I never once felt bored. As the season progress's, I look forward to each new episode and what it brings.
