At the very least, you could watch Doug Walker's Vlogs on the series. He's recently finished the first season, and he does a really good job detailing what happened in the episode and why he did or did not like it. They usually range from 9-12 minutes, so it shouldn't be too time-consuming.

I will say this, early Alien Force did feel like it had tension and an over-arching story. It also felt like a continuation of Ben as a character—he's cooled off, grown up, and moved on, but he still will get the job done. After the Highbreed story, though, the show got annoying. I haven't gotten around to watching Omniverse in its entirety, but I did like what I saw.
