How should I deal with critical comment that may affect on my research path? A few days ago I posted a question on specific paper on RG. Another researcher says this is insulated paper that really shocked me because it is central to my research.

After I saw this comment I contact this person to get more explanation that may guide me but he didn't respond.

The paper name is "Multimodal Registration of Remotely Sensed Images Based on Jeffrey’s Divergence, 2016" and my interest is multimodal image registration, below you will find a screenshot for the discussion.


I post this question to get some advice from senior researchers that may pass through a situation.

Update: How can Q1 journal accept to publish insulated work?

Thanks
"Insulated" is a strange word to use there, but that reads for all the world like "This was a one-off project for me I don't really work on anymore".

Many academics end up having those. It doesn't mean anything about your research, and definitely isn't "shocking".

To respond to your edit, one-off or isolated projects aren't inherently better or worse science than any other project, so there's no reason a top tier journal wouldn't publish someone's side study. Indeed one of my best publications is from a one-off project.
