Not bad at all, just let down by being very BBCified.
The adaptation is quite excellent, it's just bogged down by a bit of a hammy script, and the count starts as this superbly mysterious character that quickly devolves into a BBC cor bleedin' blimey type villain which just doesn't fit with the rest of the show. Just needed a bit more thought into the villains script as it felt a bit of an insincere villain cop out with naff one liners. Van Helsing keeps this show afloat, so well written and performed. Definitely worth a watch as the cast is unbelievably good, if it had just been a bit less obvious and adopted the less is more horror mantra it would have actually been quite terrifying.
