It’s pretty ridiculous hype. Joking aside they are ok but it’s very basic music and lyrics and they’ve built the image around supposed rivalry.
The best comeback gig of all time was Led Zeppelin by a country mile. It’s just a laugh in comparison.
It's not really ridiculous if the appetite is there though, is it? If it was Blue or The Cheeky Girls getting this attention then you'd be right. But whether you like it or not, they kind of defined an era/generation so the hype is warranted.
In terms of the basic-ness of the music and lyrics? I'd agree to an extent on the music but some of the lyrics are classics. And 4 chord songs can resonate with many more people than more complex pieces of music. A basic shortbread recipe doesn't mean it's not f*&king ace to eat.
Being early/mid forties, I wasn't really aware of LZ when they were around so their reunion pretty much escaped me. The one thing I would say is that wasn't there 30 odd years from them falling apart to getting back together again? That's double the amount of time Oasis have been split up so the desire for a reunion for LZ built up over a longer period of time - great anticipation etc.
And there's a fair argument that LZ were/are bigger globally than Oasis - I'd listen to that argument. Could the same be said about the UK? And what I mean by that is, perhaps the LZ reunion was 'bigger' in your eyes as there was more interest globally? I don't know the answer to that, just surmising.
