No, she's not a video tape. One of her skins shows her recent arrival in the US has apparently given her quite the dump truck ass. Must be all the McDonalds. Her skill powers her up with extra stats relative to the enemies she's fighting, meaning she has basically no real use vs. mooks. Potentially handy vs. bosses, but being a RoF-focused AR, she suffers from chips existing.

She's basically AUG, but without the random fire mechanic. Which makes sense because she has an AUG. This logic doesn't work for any of the other girls, but shush.

If you'd like an evaluation of AUG to get an idea of how good Angelica is, here's AUG's article.

On one hand, her passive debuffs the enemy quite nicely. On the other hand, her stats kinda suck, and her active is basically a glorified stun, and yes, anything immune to stun is immune to her, too.

Since EN lacks the chip, she actually has good DPS. Once EN gets the chip, her DPS is kinda meh.
