I would have loved to see a "before he lost it" episode, where Garth is a functioning and talented captain of a starship. Inhat could definitely have pulled it off.
This episode is one I enjoy a lot for a number of reasons, but it's not my favorite for quite a few more. There are some seriously flawed aspects and terrible SFX is leveraged as well. But the good points still make it worth watching. I just try to ignore the rest.
