Too many variables

I acquired this 28mm Hanimar lens with M42 that fits on Pentax so I teamed up with the Spotmatic, loaded up with some Era 100 Chinese film I recently bought [cheaply; very cheaply actually] and shot away.
Not sure about this combination! Either the focus on the lens is off or the film is rubbish. [or of course, I'm a rubbish snapper] I suggest its the latter.
Anyway, here's a couple of snaps -from in and around my home :-) - from this combi, sloshed in ID11 [which i had never used before].
Next time, i shall try one new thing at a time !
