"Hold Tight" starts promisingly, but soon slows to a crawl and the story doesn't seem to advance for at least 2-3 episodes (out of only 6). It also has an unwelcome emphasis on women getting kidnapped, beaten, murdered, and in general victimized. There are a couple of interesting twists near the very end, but it may be another case of "too little, too late". Well-acted by all, but a disappointment in comparison to other recent Harlan Coben series, including the also Polish "The Woods" (with which it shares two characters). 6/10 on the whole.
