Just got back, and I'm actually a lil disappointed brehs.
It wasn't as wild, gruesome or scary as I expected. Decently done, but overall it felt pretty standard. First impression is that this film influenced the beyond quite a bit, but Fulci made the better film, obviously.
I keep thinking about the film Alucarda. Personally, I can hardly sit through Alucarda, but certain scenes and scares in that film are basically etched into my head. On the other hand, while I enjoyed the sentinel in its entirety, it just sort of fell flat, which is crazy because the pacing of the film leaves little room to ever really get distracted or bored. I'm not sure if I rate the sentinel higher than I would Alucarda.
Anyways, some memorable scenes, but I just can't rate it too highly. I'll give it another shot down the line, and maybe I'll appreciate it more.
Also I think a remake for the sentinel would totally work today.
