Well, there aren't actually any lyrics I dislike, to be fair. It's more that there are just a crapton of lyrics that I just don't care about, that don't resonate with me whatsoever. I hesitate to use the word 'boring' so as not to offend fans as I'm sure there is no shortage of lyrics I enjoy that click with me that I'm sure some people would also scoff at, so I get it, but that about sums it up to me. Outright 'bad' lyrics to me are things like 'day after day, night after night, replaying the events, did they ever see the red light' but there's nothing in Threshold's catalog that hits me like that. There seem to be lyrical themes to the band that just don't do anything for me, so that could be why.
Whew. That was longwinded. So, to answer the question, assuming by 'don't like' it means 'lyrics that just sound like filler to me' - oh yeah, definitely. As much as I love DR, the bottom 4 songs in my ranking leave me cold.
