>Seth Rogan as Allen the Alien
That just does not sound right. Self-satisfied stoner douche voice does is not a good match for the character.

It's pretty good take on teenage super hero. Personal life and super heroesics are balanced out pretty well, and despite being a flying brick there are still real stakes involved. Consequences of being a super hero will have on a personal life of a teen and young adult are handled much better than in any Spider-Man comic for example. Peter Parker is somehow able to function without sleep, get straight As, work as a photographer, work on vaguely defined science projects, hide his secret identity from friends and relatives for years, and somehow develop skills in fields of chemistry, biology, engineering, hacking, material science, physics, bomb diffusion. Mark from Invincible struggles with lack of time to do schoolwork, maintain relationships, and his constant busy schedule has real consequences on all parts of his life. Plots are far less "A to B" than big two comics too. In invincible each character has their own agenda, and their paths intertwine with Mark's life and duties. Art is very good too, especially when Oatly gets into the goove after issue 40 and becomes less reliant on reusing artwork.
Unfortunately, like all Kirkman's projects, Invincible begins to deteriorate with time. Drop in quality begins around issue 90, and then reaches a plateau somewhere between 110 and 120. Book goes from very good, to good, to mediocre. Then it just keeps bouncing between above average to below average until the story ends. Still better than vast majority of capeshit that Marvel and DC put out at the time. It is also relatively pozz free, or even straight up "problematic" until issues 100.
