I realise why I hate this so much, and I think it's the drop.
Yeah, it's a short coaster, but no shorter than the mini Dive coasters B&M are pumping out. But I think the reason I don't dislike the short layouts on those is because the drops at the start are fantastic, and that's the focus. But these twist and dive drops are, in my opinion, pretty terrible. Well, at least the two I've ridden are (Flug and Swarm). I think if this coaster has a slow turnaround at the peak of the lift, and then a straight vertical drop (akin to the Big Dipper layout Mack showed off), I wouldn't mind it.
