I found The Mimic suspenseful. The jump scares were well executed and not overdone. The acting performances were on point. The camera cutting back and forth to things that are not there helps with the imagination. The creepy little girl was cuteness overload; I adored her. Does the film have clichés? Umm, yeah, pretty much 90% of horror films do. The closet, the mirrors, the voices etc. But here it was very well done and those tropes came in when appropriate in the story. Not just random occurrences like many B-horror films often use. So here they are effective in my opinion. I appreciated the film wasn't campy or riddled with CG. I think the reverse mirror image CG could have been better done.
This one is definitely worth streaming.
