A rather straight-forward sequel to Bondarchuk's Attraction. There are some reveals and twists in the first half that cast a different light on the ending of the first film, but that's little more than an excuse to redo the whole invasion thing with the same cast all over again. Plus a handful of novelties to keep things interesting.
Where the first film started with a bang, Invasion keeps its most impressive scenes for the finale. This may be a bit more traditional, but it also makes more sense this way. The only downside is that the middle part feels a little lost, as it's mostly just a plot transition between the reveals at the beginning and the big finale at the end.
The hefty budget is definitely a plus, the visual effects looked pretty impressive and it's always nice to have the proper level of destruction when an alien race invades Earth. The soundtrack is decent, though a little too poppy, performances are solid but nothing remarkable. Overall a fun and entertaining blockbuster, looking forward to the third (and possibly final?) part.
