No, This is actually quite common and just an example of commercial black and white developing. The lab I used was no better or worse than many others. They do a splendid job with C41 and are quite cheap. To get a better B&W I would have to have gone to someone specilising in it and paid 3x the price, at least. You do get what you pay for.
I shot at 400 ISO but warm chemistry would effectivly have pushed that to 800 and so the negs are quite dense.
Generally when I take photos they are to show what one can expect of a particular camera and perhaps how to use some of the features. As this is a simple cheap camera that someone getting into film photogrpahy might have as a "my first film camera" and indeed "my first B&W film" using a cheap and cheerful lab is in keeping with what an average or new consumer could expect. In fact most first timers would likley be pleased with these results and I'm not so unhappy with them myself, one thing is for sure looking at them, they are not taken with a phone! Not looking digital or phone like is the aim for many going into film so job done.
