ANONIs vigil series season 1 worth watching?
I enjoyed it well enough, although I actually think season 2 is better. If you're a regular whodunnit watcher, you might be mildly disgruntled at a couple of aspects in season 1, but it's still a fairly compelling watch imo.
Is it small plot holes or i can’t just ignore that ones.
Not plot holes, although there may be some of those that I didn't notice. It's more to do with the pacing of the investigation (trying to be vague so it doesn't ruin anything for you).
Heavy (but still somewhat vague) spoilers:
::: spoiler I remember it being a new suspect practically every episode type of deal; knowing they're probably going to be ruled out by the end of the hour gets a bit old. Season 2 tones that down a bit. spoiler
