Me and my 13 year old, who has watched the animated series multiple times just watched the first episode and we both enjoyed it. Not sure what everyone's beef is with it, really.
Obviously it's going to have to diverge from the original in some ways, it's going to have to be truncated, and with a budget for a 2 hour blockbuster spent on 7 hours worth of TV episodes, the effects won't be perfect, but there's nothing I've seen so far that's jarring. Maybe we're all spoiled with good CGI in 2024, but I can still watch my favourite 80s films with obvious practical and optical FX without that spoiling my viewing experience.
