Here's what they built (this past couple years) in the Cleveland-Akron area (St. Peregrine's) --

Looks like a cross between Prot and Novus Ordo.





and here after they added a Resurrexifix above the altar --

Right.  Obviously it could be improved some with Catholic art work, but the design / structure of the sanctuary, and the small windows (without stained glass).  Structure looks grand and big from the outside, but on the inside it fails to edify.  They could have made a much lower ceiling (unecessary to be that high) and could have spent the money on making it look more Catholic and to be more edifying.  It feels like you're going to Mass inside a High School gym.

Are you sure that is a Resurrectix?  It's too blurry for me to tell for sure.

Did the SSPX build that church or purchase it as a building?  If purchased, its new 'decor' is devoid of anything tasteful, and it hardly raises the mind to God.  If it was built, then it's just another 'nail in the coffin' for anyone who would still think the SSPX is remotely 'hardline'.

Here are the two big issues I have with their big expenditures:

1) As you said, lots of chapels could use upgrades across the country.  What's worse is that there's been a history of SSPX diverting funds collected by people at chapels to their other projects, i.e. embezzling.  I know of several cases where the people at a chapel had major fundraising for a new church facility, but where the money evaporated and disappeared, and where decades later they still had no church after having raised hundreds of thousands, but then had to re-start their efforts.  SSPX have fine print everywhere that they own the chapels and can do what they want with the money, but this still is IMO morally THEFT, as the people had donated and raised the money for a specific purpose, and had slaved away in some cases for years at fund raisers, etc.  Alternatively, there are many areas where the money could be used to establish a Traditional Catholic presence.
