Sadly, yes. It's plagued by externalities, the replicability crisis and a narrow minded neoliberal paradigm. It suffers from it's own dogma, austrians especially. Deregulation is a key focus of austrian economics and its penispolishers despite the overwhelming dangers it presents. Instead of obvious corrections to identify safe limits between catastrophic deregulation and strangling over regulation they just spew the dogma and ignore the tragedy. Being co-opted by the fascists isn't helping.
I was trained as an ecologist, and when I started digging into economics from Smith, Malthus, Keynes, Ricardo and Veblen I could start to see the mindset and could appreciate the insight an early incomplete nascent understanding of the field could bring.
When I started following modern economics it felt less illuminating and more tortured. Conclusions were wrong and dangerous things were being said. Stupid things were being held as truths. The reductionist view of translating everything into dollars and GDP without measuring the impacts of events and policies on systems, the people in them and the environment. The deliberate ignorance for economics refusing to adapt to advances in other disciplines. It's as siloed an ivory tower as it gets.
When you can say the economic consequences of climate change can be mitigated by moving everything to airconditioned indoors for 5% of GDP and get a "Nobel" Prize, well, it puts the entire field in disrepute.

Steve Keen says it better than I ever could.
