Than let's all pray the show gets more budget for effects (they seem to have, around after the time they won their 2nd People's Choice Award as favorite Sci-fi/Fantasy show). Because like it or not, the special effects for the fight scenes are expensive and the show's low budget is a significant debilitating factor. That's why Lilith breaking most of the seals being opened, the fights or skirmishes between angels and demons in S4-S5 are behind the scenes, and possibly why most of the fight scenes with the big bads are either very short (Dick Roman) or completely never happens (Michael vs. Lucifer). The same goes to why angels must wear vessels, why hellhounds were invisible during the early seasons, why demonic biokinesis was only through hand gestures and no visible light shows or shock waves, etc.
