I haven't paid much attention to Swamp Thing since the days of Bernie Wrightson, but this teaser trailer for the upcoming TV series looks promising.
From Ars Technica:
The DC Universe series stars Crystal Reed as Abby Arcane who, in the comics, is niece to arch-villain Anton. According to the official synopsis, she's now a doctor with the CDC who comes back to her hometown of Houma, Louisiana, because of "a deadly swamp-borne virus" ravaging the area. She teams up with fellow scientist Alec Holland to investigate—and just like in the comics, Holland is killed. Except he might not really be dead, as Abby learns more about the mysterious, likely supernatural nature of the local swamp.
We don't learn much more from the first teaser about just how Swamp Thing will be reimagined this time around, but the writers are clearly emphasizing the horror aspects. There's no dialogue apart from horrified screams of various folks who encounter something terrible—probably Swamp Thing, but there could be other monsters in the mix.
