Hidden Frontier features fan-created live-action Star Trek episodes depicting the latter-day adventures of the U.S.S. Excelsior, setting during the Star Trek: Next Generation/Deep Space Nine/Voyager timeline. The visuals are impressive considering these are fan-efforts, and while there's the occasional green screen halo, over all it's amazing how much these devoted fans have been able to accomplish. There are seven seasons consisting of six episodes each.
