Roger Ebert does not like Battle: Los Angeles:
The aliens are hilarious. Do they give Razzies for special effects? They seem to be animal/machine hybrids with automatic weapons growing from their arms, which must make it hard to change the baby. As the Marines use their combat knives to carve into the aliens, they find one layer after another of icky gelatinous pus-filled goo. Luckily, the other aliens are mostly seen in long shot, where they look like stick figures whipped up by apprentice animators.
In fact he reads it out of the sf genre, saying:
Here’s a science-fiction film that’s an insult to the words “science” and “fiction,” and the hyphen in between them.
And he knows whereof he speaks — about science, about fiction, and especially about the hyphen. Here you see Ebert seated beside Walt Willis (lower right) in a photo from 1955 (via Fanac.org):
