I legitimately liked to do it 2-3 times per visit, more than the coasters. It was just fun ok, it wasn't the best log flume, but it was my favourite thing at Thorpe after Stealth.
My controversial opinion: the Walking Dead The Ride is a great ride, and one of my current favourites at the park. I think it gets over-hated because the thene doesn't suit the family coaster track, but other than that I think they've pulled it off really well.
