I think the IMAX at Providence Place is one of the better ones around if you're willing to go that far. You can look here to compare. https://lfexaminer.com/theaters/ or https://en.wikipedia.org/wiki/List_of_IMAX_venues#United_States

If you're willing to go a bit outside of Worcester, I've had excellent results from https://wecarecarcare.com/ (Framingham). Prices are reasonable and I'm very happy with how my cars looked afterwards. No relation to them, just a satisfied customer.
