Overall, I think it was a good anime, especially for those who are still a bit new to the world.
For more experienced anime viewers, let's say that if Rize's kagune could talk, and Ken Kaneki had a harem of oblivious girls, then it'd be Parasyte. Essentially, Parasyte is a prototype of Tokyo ghoul with a slightly different theme.
Parasyte tackles some thought-provoking themes (e.g. nature of humanity, the natural order, environment) and comes to controversial yet likely true conclusions about them. However, I found that sometimes these themes were introduced a bit to rapidly or became the focus solely in the later episodes.
My main qualm was that many of the supporting characters were never truly developed and oftentimes would disappear and reappear sporadically. However, there was significant character development in the main ones, which was done well.
Overall, I think it's an anime definitely worth watching. I think the first ~8 episodes were amazing, middle episodes made me want to stop watching at points (the only thing that kept me going was the suspense and action), and the last episodes were pretty good. Suspense is definitely played well, and I like how all of the manga has been adapted into this series, so we get closure at the end.
