Nonetheless, we see two possible periods for the premiere. You may have noticed that the previous seasons started off in July and October, respectively. As a result, we have every reason to believe that the upcoming premiere is slated for this fall, likely in October of 2018. However, this is nothing but our forecast. So, we'd like to wait for the official news from Syfy to clarify the situation.
Frankly, many doubted that Van Helsing has a chance for another round on Syfy since the 2nd season premiere has lost about 63% of a target audience. However, as we've seen, the network nevertheless has opted to pick up the horror drama for a next installment. Indeed, the premiere has garnered less than half a million viewers (0.459) with a 0.15 demo rating among adults 18-49. However, even given the fact that these figures don't look impressive, they are entirely acceptable for such a cable network as Syfy.
Besides, the reaction of the target audience was much better versus Season 1. On Rotten Tomatoes, the 2nd chapter of Van Helsing holds a score of 3.7/5 and a 66% approval rating among the viewers. At the same time, on Metacritic, the rating was also favorable, 7.5/10. Therefore, nothing is surprising that Syfy made such a decision. On IMDB, Van Helsing has an overall score of 6.0/10 > 10,400 votes. Most likely, the network paid more attention to the response from critics and viewers than to a significant drop in the viewing audience. Such approach could eventually explain the favorable decision.
There is no official synopsis for the upcoming season of Van Helsing so far. However, according to the official announcement, you should expect "amazing adventures and a few new surprises as well." Besides, there would be more blood while the humankind would be close to "the edge of true chaos and utter darkness."
