Some of the fast motion stuff was funny. For some reason 3:27 cracked me up seeing that guy just race into LG jumpad on furiousheights in fast forward. Looked utterly ridiculous.
The sounds at 3:13 are funny too. A lot of potential for comedic value there imo.
Watched it after this comment, and you're actually pretty spot on here.
While overall it isn't great or anything (sorry) there are some elements that for sure would fit into a "serious" frag movie. The slow mo close ups of the enemy models, some of the editing effects, the slomo rewinding and distorted sounds and probably more that I missed from a first watch.
