Jimmy Page, It's time to call your lawyers?

I'm pretty late to this party--as usual.  A Chicago radio station is starry-eyed over Greta Van Fleet.  I gave them a listen today.  All I could think was...

Is this a Zeppelin parody band? 

There are so many features to their sound, playing, and sonics that sound just like LZ--so much so that I cannot get into the music passionately.  These are (IMHO):  Vocals (phrasing mimics Robert Plant without stopping);  Lyrics (the themes seem, based on limited listening, to track LZ);  Lead Guitar (I cannot think of another guitarist who sounds like he's trying to sound like Page as much as this one).  

Does Greta Van Fleet sound like a facsimile to you?  I'm not hung up on punishing artists who copy, as I think it's part and parcel of the art form.  But I'm having real trouble getting past the photocopy nature of this.  Again, this is just one person's opinion. So curious to hear what others think and feel about this group.  I'd like to give them more of a chance and maybe others can help.  For now, I can't keep listening.
