Is this install garbage?

I'm having the HVAC installed in my new construction home in NY right now. Since I'm having the house insulated with spray foam I am having an HRV installed and that is where my issue is. For the HRV they used insulated flex pipe to connect to the heating ducts and to do the intake and output air to the outside. The pipe is all bent and twisted in ways that I don't think are acceptable. However, I've never seen an HRV installed and I don't know if it makes a difference or not. Before I go demanding the fix anything I was hoping to get some feedback from other people on whether or not they think this looks acceptable.

Here are some of the photos I took:

Flex duct needs to be well supported and run with as few bends as possible to prevent airflow restriction.

I understand that. The contractor is saying it's fine because it's only an HRV so the restricted air flow is still plenty. Is that true? My builder (who did not hire the HVAC contractor, I did) is saying it's junk. Any outside opinions would be greatly appreciated as I've never seen an HRV installed and know very little about how much air flow they need.

Every 90 degree turn should have a ridig sheet metal elbow. With that short of runs I would've ran them in sheet metal.

I would have preferred all hard pipe.

hard pipe is 3x the cost and a LOT of duct leakage.
I don't see any mastic seal. ducts should not be restrictive and leakage mininized by mastic seal.
this is a basement install??

best of luck
