It definitely doesn't seem as if Freaks and Geeks will produce any truly bad episode, but this was definitely one of the lesser episodes the show produced. The show took two plots that were certainly interesting enough and ended up not living up to its promise. I actually liked the geeks plot a bit more than the freaks this episode, mostly because it had the perfect level of awkwardness and drama. Also because Bill (played great by Martin Starr) is the perfect deadpan actor.
I thought that the plot where Daniel attempts to pass his algebra test was extremely under-developed and it wasted a lot of possible funny moments. The last two episodes haven't been as funny as the first three, although that's not exactly detrimental to the show. Instead, it gives an interesting tilt of drama to a show that was at first just comedy driven. I did like how James Franco told the same story about being a dumb kid in school to two different groups of people and makes Lindsey laugh hysterically.
As I mentioned, I loved the way they used Tom Wilson in this episode.. the guy who played Biff in Back to the Future seems to have finally found another role that allows him to be irritating yet somewhat likable at times.. okay, perhaps Biff was never likable, but at least this was good. And watching Sam, Neil and Bill watch porn was hilarious.
Overall, the episode definitely wasn't bad, but to me, I thought it was a bit heavy on the drama without making up for it with any substantial humor.
