You can watch All American on Roku TV either on the Roku TV set or using the Roku media box. Right now, you’ll be watching reruns, which are available on Netflix. The show originated on the CW channel, which you get with Roku TV and it’s also available on Netflix. Season 6 won’t debut in October due to delays caused during the Writers Guild of American Strike that lasted from early May through September 27, 2023. Once production schedules and logistics are sorted the new season will be in the works. Estimates are that it may not debut until early 2024. Meantime, if you subscribe to Netflix, you can watch the previous season again or try this show for the first time and get caught up.
