Re: My Trek Through Enterprise: Season One There's definitely no need to watch all of S2 unless you really want to. Just be sure to check out "Dead Stop" (easily one of the show's top five) , "A Night in Sickbay", "Singularity" (optional), "The Catwalk", "Stigma", "Cogenitor" and "Regeneration". Though if you do watch S3, might as well add "The Expanse". ... I remember watching "Shockwave, pt. 2" and the Smallville second-season premiere rather close to each other. The quality gap was pretty embarassing for ol' Team Trek.
