10 Worst TV Shows To Launch This Decade
8. Constantine
When it was announced that a new, more authentic interpretation of dark investigator John Constantine would be hitting the small screen, fans cast aside the memories of that Keanu Reeves clunker and got devilishly excited. But while the early signs were promising - Welshman Matt Ryan signalled some shrewd casting and Neil Marshall was brought on-board to direct the pilot - each episode that followed said opener was a plodding exercise in iffy acting and derivative dark arts action.
NBC moved fast in exorcising this one, with the show being cancelled in February 2015, following a lean one-season run. It's not all doom and gloom, though, as Ryan was been brought on to guest star in an episode of Arrow.
