Jens Holze’s review published on Letterboxd:
The first one was kind of weak and this one is in no way stronger in my opinion. It basically has the same plotpoints (without any need for introduction), the girl's in danger along with almost everything else because of some bullshit mcguffin that I already forgot about. It just feels random. Even the great actors (and there are some) don't get to do much, the look is familiar at some point I thought I was watching Episode I: TPM. Hiddlestons Loki is fun, but nothing else in this film really caught my eye, not even Natalie Portman. So I guess it's a necessary step towards the next Avengers movie, but that's it.
