I genuinely really dig Crystal Skull (I'm also a Star Wars prequel enjoyer, so I guess 2000s-era Lucas just does it for me; I miss having his voice in cinema and I really hope that he is making those indie films that he always talked about to screen for his friends).
Dial of Destiny's biggest problem, in my opinion, is that the directing is never really as kinetic or lively as Spielberg's. Not to knock Mangold, I'm a fan of him in general, but Spielberg's absence is noticeable. Ford gives one hell of a performance, though, and that movie is really his baby at the end of the day. I enjoyed it on first viewing; haven't seen it since but I'm sure I will end up watching it again down the line.
If Raiders is the ultimate throwback to the pulp serials that inspired Lucas (and potentially my favorite Spielberg movie, full stop), then Temple of Doom just straight up is one of those serials brought to life in the (then) modern day (problematic representational elements included, unfortunately). It has a lot of appeal to it as this rip-roaring adventure that's just always on the move, and also doubles as a pretty horrifying 80s fantasy movie. There's so much to love there, even though it isn't quite the masterpiece that is Raiders. It was my favorite Indy movie as a kid, and I'll never second guess myself as to why that was the case - there's a crazy mine cart chase, lots of gross bugs, and a dude gets his heart ripped out, for crying out loud!
