It looks really nice for the young families, in my opinion! The station and queue look very nicely themed, and powered coasters often have really good universal appeal, in my opinion; you see people of pretty much all ages riding and enjoying RMT at Alton, so while this perhaps doesn’t look quite as thrilling as RMT, I think it could be a very good crowd-pleaser for Efteling’s more family-orientated demographic! I also think that the interactions and dueling elements could offer a fun and unique twist on the ride type; as far as I’m aware, isn’t this the first time a dueling powered coaster has ever been built?
If I was to offer a minor criticism, then I think it could perhaps have done with a bit more theming during the ride itself, but I suppose the planting they’ve done will probably grow and hide parts of the ride over time, and it could offer some nice near miss opportunities with the ride once it’s grown a little!
On the whole, however, I think it does look like a really nice little ride for its intended audience!
