The movie is not intresting till the interval.After interval the twist of the movie begain . But still the movie is not so good .as compare to 1920 1st part.Also, 1920 London is very similar to the first installment in the franchise. While in this one its the wife who saves her husband, the first film had the husband saving his wife from an evil spirit.
The songs arent that bad but a horror film is supposed to be crisp and to the point, without any distractions. Thats one of the prime reasons why horror movies should not have songs, even if there is a love angle.
