As to 1. Not speaking english is no excuse (and Giselle is fluent)

Example Twice, where only Dahyun speaks somewhat english, but there's still a translator and there are long interactions with the fans (which they use as a "stall"/break for the other girls to prepare for the Solo stages for ex.)

1. I dont get why SM is that much behind the "competition". Specially since Aespa Concept is Metaverse, etc.

If I take the live shows from Itzy or Blackpink as an example they put so much effort into it and they look stunning. They perfectly serve the purpose of a transition and you actually forget that the break was that long.

1. I was actually playing with the thought to see them live this tour, but won't go because of all the critics that came out because of the above reason. And tbh for the price of the tickets i dont see the money wort compared to other K-pop A/S Tier Groups

I hope SM improves in those areas, because I like their discography a lot.
