Pretty neat actually. Definitely knew that they didn't have a gem on their hands though with how this thing was marketed only in the few days before it released (and in actuality, not at all).
Again, not a bad thing, but it's telling for sure. It absolutely felt like a side story, which was clearly intended, so that's all cool.
I'm really hoping they do take some time and a bit more effort in the writing department for the next one but like Boom said, it looks like they're gearing up for it already. As long as they don't just go on milking it and actually expand what little yet cool universe they've created, I'm down for whatever they're willing to try.
Reviews were obviously making this out to be a flop but also seemed very much like they were looking at this movie the wrong way. It's not "the next Cloverfield". It was a "Cloverfield side story". Viewing it like that, it's nice. Standalone, not bad. Comparing it to the others...a bit meh.
