Some of the soundtrack choices were cringe. Especially since two of the tracks were ripped straight from Guardians of the Galaxy and are tracks from the 70s...
And no, it wasn't just IMAX. I was in an XtremeScreen session and his audio was fucked. Couldn't understand shit.
I recognized one from Guardians of the Galaxy (Spirit in the Sky), either I didn't pay attention or forgot what the other track was.
I'm hesitant to say that it ripped off GOTG since it's all licensed music, but the movie does seem to draw some parallels to it that stuff like that makes it more pronounced.
What ultimately separates both movies is GOTG feels genuine and had a lot of love, Suicide Squad is like the fucked up mirror version, pretty much like Superman to Bizarro.
