The bat would be computer enhanced. Barnabas' hand certainly wouldn't look like a cut-out. And, for cryin' out loud, get those candles to blow out on cue! I always thought the make-up was very well done, especially the aging process. Ironically, I think it looked far more realistic back then than what they do today. I saw a rerun of Stark Trek - The Next Generation on TNN which included "aging". They all looked like they fell into a vat of pancake goop. However, on DS, it was all extremely convincing. Barnabas, when he aged almost 200 years, looked realistic.

So did Angelique. Even Carolyn, appearing as a woman in her mid-forties in 1995, looked very convincing, with a minimum of makeup.
I was not that impressed with the Ef-X of the DS revival series. I remember the scene where Angelique, holding the bullet which would kill Jeremiah in her hand, caused it to vanish and end up in Barnabas' gun. There was a definite "chopping" in that scene. They did better on Bewitched.
