Crowning Moment of Awesome: Optimus Prime's Patrick Stewart Speech in the first miniseries and the fire department of the city then proving him correct by slamming their fire engines into the Decepticons, buying Optimus precious time. Awesome.
Deader Than Disco: The series went through this hard. While never without its detractors, it still sold millions of copies, with the original miniseries cracking the top ten in sales charts. However, once word broke out of Pat Lee's criminal behavior, public opinion of the series flipped completely into hatred. Since then, aside from War Within, the series has pretty much vanished from the eyes of both the fandom and Hasbro (outside of the occasional Sunstorm toy), and many of the writers and artists who got their start there seem to regard it as an Old Shame. Even stylistically resembling the Dreamwave comics is enough to get alarm bells going in some circles.
Ensemble Darkhorse: This series portrayal of Sunstorm was beloved and has become the definitive depiction of the character.
Magnificent Bastard: Megatron at the start of the war. After Wreck-Gar accidentally restores the memories Megatron lost in his first fight with Optimus, he becomes this once more.
The Fallen. Unpublished issues would've revealed that Shockwave, Jetfire, and Sunstorm were all just his unwitting pawns.
Overshadowed by Controversy: Dreamwave is remembered far more for its shady business practices (not paying numerous employees being one of the most known claims) and controversial bankruptcy than for any of the stories it told. The stories themselves became Deader Than Disco with many future series, IDW in particular, outshining them easily and much more attention is paid to the infamous art flaws than any of the positives.
