I mean, I guess it depends how you define early years. For me early years of IF would be the LS/Sub/TJR/Whoracle period. Put on anything from those albums and compare to THE and it sounds nothing alike, other than both being melodic and metal.
But yeah, even if we are defining Reroute as 'early' IF (album is 20 years old, so I guess some could see it that way) THE tracks sound nothing like this. Again, put on anything from Reroute and then one of THE songs. Nothing alike.
People are just really desperate to have something that sounds like older IF, because there is not and has never been anything like it. I don't think there ever will be again. You can hear small parts of what made up older IF in certain sections of THE songs - but that's all. You can say that about many songs and bands over the years. Even some Black Veil Bride songs can briefly sound like older IF. It doesn't mean the overall song or band sound anything like them though.
For me THE is in that vein of Swedish MDM from the mid-2000s. It doesn't sound like 90s MDM at all (listen to classic ATG, IF, DT, Arch Enemy, Night in Gales, etc... totally different sound). I'm OK with the mid-2000s style as I still liked that sound a lot. But if you're going to compare THE to any band it'd be DT - Stanne plays a part in that, but just listening to the song structures and types of melodies there's a gothic tinge which was always DT's trademark. Those 'happy' melodies that defined classic IF, and the AOR-influences that permeated Soilwork of that timeframe aren't really there in THE's music. The former only in brief bursts, the latter not at all.
Imagine Anders or Speed's vocals in place of Stanne - do any of THE's currently released songs sound like an IF or Soilwork song with those vocals? Not for me.
