Still, this movie is supposed to link up with the Venom movies (of which, I found the first one entertaining and the second one less so), perhaps the MCU (as Micheal Keaton is supposed to make an appearance as Vulture--a character he played in Spider-Man: Homecoming), and quite maybe the Amazing Spider-Man universe with Andrew Garfield (an idea that has gained traction after Spider-Man: No Way Home). The movie also has quite a few actors whom I like; however, some have ended up being in poorly done comic book movies before (I'm looking at you, Jared Leto). It has the potential to be good.
... Except the studio has it on a review embargo. Even though the movie is due to come out in under three days, critics have not yet been allowed to release their reviews. This is frequently a sign that the reviews are going to be quite negative. This way the studio can still get a decent opening weekend showing and recoup some of its costs before the negative reviews come out.
Now, not all review embargos mean that a bad movie is coming out. Sometimes, studios do this to keep a tight lid on spoilers for major surprises. However, considering the quality (or lack thereof) of the trailers, I think that this embargo is more likely a bad sign.
