Yeah I agree certainly looks impressive for a fan production. Certainly got a lot of talent on-board which bodes well.
I really liked the new films, well cast and acted with very good scripts. They handled the change in timeline pretty well, enabling them to skip past some of the huge mistakes made in the earlier film franchise.
The only downside is they overplayed the handover bit with Spock but aside from that it works well and I look forward immensely to the third instalment.
I will follow this closely and I am sure I will enjoy this as well, now all we need is some well funded fans to produce a really good Firefly film/series
