I really doubt he’s necessarily the problem. From everything I’ve been hearing, it’s an overall problem with everything not including special effects and soundtrack. And when I kinda think about it, Leto mostly just ends up in terrible movies that are bad and would’ve been bad even if someone else was in it. The first suicide squad movie sucked and Leto was barely in it, Morbius sucked, but it was gonna be a turd no matter who was in it. Look at all the other Sony flops like Kraven or Madam Web. Nobody could’ve saved morbius.
His problem is that he keeps saying yes to garbage and I think that’s really what’s killing his acting career.
